  1. I think that they should fine you just for the number plate.
  2. and it sounds like the NP calcs have developed a bug See extracts below from the wattage forums 2009/12/18 Chris Cleeland <chris....@gmail.com>: > On Thu, Dec 17, 2009 at 5:00 PM, Nate <n.......@gmail.com> wrote: >> So what is the best way to handle data from a PT to use your NP >> algorithm. > > it's not data from the PT that's the problem--it's data from a PT when > the sampling rate is anything other than 1.26s (or whatever the most > frequent sampling rate is). Except, Nate's file is 1.26seconds, and should be producing the correct value, and it certainly looks to me like WKO 3.0 does get the calculation wrong. I suspect this due to new code which attempts to deal with irregular sampling rates, and is fooled by the non multiple of 1 second nature of the PowerTap into thinking some of the samples cover more than 1 second. ie: WKO 3.0 thinks there are these whole seconds: 1,2,3,4,6,7,8,9,11 and for the 6th second it considers that a sample for the 5th and 6th seconds, and the same with the 11th for the 10th and 11th seconds. Doing this for a range of the file and calculating myself, I get an NP value the same as WKO 3.0's. I would say this is a WKO 3.0 bug, and if you have a PowerTap recording at 1.26seconds, stick with 2.2. Jim. and ... My PT is recording at 1.26seconds - a 2hr:49min ride yesterday gives NP of 249 in 2.2 and 255 in 3.0. A 20 min interval within the ride is 297 in 2.2 and 300 in 3.0. and ... I have NP discrepancies with my SRM (set as 0.5 second sampling rate) as well. These are smaller in magnitude but cause concern none the less. ie 60 min period 2.2 - 261W 3.0 - 267W data handling or calculations do appear to be different between programs and Coggan explains ...

After digging into things a bit more, there does indeed appear to be a problem with the way that WKO+ 3.0 calculates normalized power from data recorded using a legacy (i.e., non-ANT/ANT+) PowerTap. This bug does *not* affect the calculation of normalized power from data collected using any other device. A fix has already been developed and a new build will be released as soon as it can be adequately tested. Andy Coggan Windbreaker2009-12-18 15:04:15
  3. Willehond, don't do it yet. Try the GoldenCheetah stuff when they release a new version in the next few weeks. It won't cost you a thing. I see that WKO is now starting to incorporate some of the GC functionality now as well. Nothing wrong with WKO, just that GC is going to leave it behind shortly - it has a ton of support now.
  4. So what would you say to having the ability to race against other guys & gals over the internet? That capability is only a matter of weeks away for those of you with power meters with Ant+ capability or even computrainers. You also need an internet connection of course The developers of the opensource power & training software, GoldenCheetah has just included a "real-time" capability allowing it to read directly from your Ant+ power meter. It is PC based software so the next step is to build the server capability to link all the users together. If the trainer racing isn't exciting enough for you then at least you can use the internet capability to "train virtually". The days of slogging through your indoor trainer sessions on your one-some during those dark winter days are gone. You will now have the motivation of using your competitors as motivation. It is also going to create a whole new dimension to virtual coaching bringing back that personal touch where your coach can monitor you in real-time rather than just reviewing your data after each session.

  5. I read your post very carefully, and took exception. You on the other hand don't seem to read posts very carefully - where did I say anything about a pub. The beer is cold and it tastes just great. What was that earlier comment you made about personal insults? Over & out bru.
  6. No cheap shot. You make the decision to use his name & memory to support your waffle. But you are right this is not about motorists, so we should all start a thread every day berating cyclists and stirring up sh*t just for the sake of stirring up sh*t - that certainly will change the underlying problem.
  7. GoLefty, I didn't intend to respond on this thread nay longer but ... a) If satire or humour was intended in the first post then it was in poor taste to use the death & memory of Chris Atwood. Poor taste. b) If satire was intended besides a) above - you got hopelessly lost because the post really just came across as flatly insulting. Good satire doesn't only insult. A bit of advice, I'm certainly no literary expert but from watching the demise of the likes of Deon Maas and Jon Qwelane who are "profesional jouno's" that couldn't hack the satire thing, stick to the technical posts - they are your strong point. c) The "road cylists are the pits" line has been flogged to death. You and others supporting your point, accept that generally, South African road users are the pits, so why should we single out road cyclists as requiring specific attention. The problem is much bigger than cyclists, and to make it a cylist specific issue is actually quite self centered, which in turn is a root cause of the bigger problem. The bulk of South African road users are generaly selfish and inconsiderate ... full stop! We think that our rights, our cause, our situation is/are more important than the next guys. d) Then the bit that really gets my goat is when cyclists advocate that any harm that comes to cyclist is somehow deserved (the throw stones at elephants thing). That is a fundamental problem that cyclists face. Of course we shouldn't "misbehave" but even if we do it is completely unreasonable for any motorist to put our safety in danger, just as it is unreasonable to take aim at a jaywalking pedestrian. The analogy is flawed. We don't expect elephants to conform to norms of a civilised society do we? Your's sincerely Mr Self-righteous! ps I'm off to have a beer with someone whose company I choose and enjoy.

  10. No not yet but it is better than the supplied PT software. It'll get there with some support. Does all the important stuff already. And here is my regular update. For those Take a look at these screenshots. http://www.goldencheetah.org/screenshots.html What isn't shown in this link is that it also now has a training stress balance graph. They are also working on adding additional training metrics as Coggans training stress load algorithm seems to have some flaws with zero power periods. Windbreaker2009-12-08 14:14:19
  11. Hey whichever form of law breaking turns you on bru.. Mostly I'd prefer it if the community called cyclists showed a little more respect for the law than we currently do. But clearly many are resistant to wanting to be better people therefore any constructive debate is impossible. Sort of like arguing with a child. PS: see how the arguement now cleverly morfs from Adolf to facism. Clever but very transparent. You mean like starting a constructive debate by generally referring to "the other side" in derogatory terms like homosexuals, thugs etc. REALLY constructive!!!! GoLefty if you are not spewing venom at Andrew McClean then it is at the PPA or when you run out of imaginary reasons you revert to taking on "roadies", and when that fails you revert to the pulling the joker card - "them racist Saffa's". Seriously bud, it's time you got over yourself. That chip on your shoulder really could do with a polish.
  12. Ok, ok maybe not Julius how about Jon Qwelane? He can at least read.
  13. I rest my case' date=' m'lord. And I support Julius Malema!! Windbreaker2009-12-07 15:05:50
  14. Ok so lets see... Is this the usual "them vs us", chip-on-the-shoulder, holier-than-thou. You whitey/roadie's are the root of all evil stuff again? Jeez' date=' I must have been ignoring those posts, cause all I remember from you is the usual "roadies are the root of all evil bullsh*t". Oops sorry, I lie, there is the occasional informative technical posting. Amen brother. But you'll do it anyway' date=' so long as it fit with your current gripe. The day that you can demonstrate that roadies are any different the other categories of road users you may have a case. There we go .. the sprinkling of racist undertones to add a bit of flavour to the topic. ... followed by a healthy dash of insult ... followed by the righteous' date=' evocative, stirring of emotions ... ... yet more preaching ... .. yep here it is - "them & us". Yes' date=' we the righteous mtb community who can do no wrong. FFS! Get a life. R100 to the first guy who spots the similarity between GoLefty's speech & Oom Eugene's this weekend ...
  15. ok, see PM for my contact details
  16. Kiwi, price & availability? I'm in the market for a bike.
  17. Maybe I am missing the point. I understand why the manufacturer would be supporting their official agent by getting tough with an "unofficial supplier". What does "import directly" mean? Do you source directly from the manufacturer? If so why were they taking you to court? Not saying that I disagree with what I think that you are doing but you should be clear about it to your customers. This is not really black & white, is it?
  18. Well done Glen! Nice touch to hang around & say thanks.
  19. Hmmm... so lemme see ... Someone whose use of South African roads as a cyclist in 4 (?) years probably totals less than 50 hours (even that would be on closed roads or marshalled events in organised events) feels the need to sort "misbehaving cyclists" out. Perhaps if he used the South African roads, as even a motorist, on a daily basis he would realise that the "misbehaving" cyclist issue is as much about generally intolerant road use as it is about individuals who happen to be cycling when they are seen to be "misbehaving". If it is genuine "misbehaviour" as opposed to some over-zealous perception then you can be sure that they behave the same way in a car. Perhaps if our crusader used the roads in South Africa as a cyclist on a regular basis he would be seen as an "affected person" and therefore his efforts would carry some credibility. Perhaps if our crusader even paid taxes in South Africa he would be in a position to voice his opinion with more credibility. Taxes are used to improve infrastructure such as public transport. Improved public transport in South Africa would reduce road congestion which would directly impact on the levels of tolerance of ALL road users. Until then it is just hot air from a bored old man in Angola who is looking for attention. ... and before the attacks start ... I do not ride abreast on narrow roads, I do not hold up traffic unless it is unsafe for the vehicles to pass. I try to generally be considerate of ALL other road users whether it be on the bicycle, motorcycle or in the car. I am not perfect and I don't always maintain a good attitude on the road - particularly when I am faced with ignorant or aggressive attitudes of road users who put my safety at risk. I do jump certain stop streets when it is safe and if it does not inconvenience others. I have been photographed riding three abreast on a quiet road somewhere in the Karoo between Cape Town and Knysna. I have also been known to ride 3 abreast in quiet country roads in the Netherlands - without motorists reverting to hooter rage by the way. But I guess that would be considered as misbehaving by the Angolan sheriff and his posse. Oh well ... I'll work on it with my shrink during group therapy.

  21. This posting from a GoldenCheetah users mail list. It's actually quite old news but ... Ok, I should probably wait for Mark to announce this but it's hit the wattage list and Twitter and You Tube so...
