Velouria Posted September 30, 2013 Posted September 30, 2013 Taking Seasonal Segments - Tailwind Strava SlaughterHad a great one of those on Thursday last week - 4 segments at over 50km/h
Sworks20 Posted September 30, 2013 Posted September 30, 2013 Okay! So I figured it out. When I eventually found it my TSS was at exactly 35.2 for the 20 minute all out effort. What's the chances of that being absolutely correct?? It is not 100% correct but for a Powercal it is correct. remember a Powercal isnt working off strain gauges its off heart rate and algerythems. whatever you have adjusted it to in order to get 35 keep it there.
Sworks20 Posted September 30, 2013 Posted September 30, 2013 Those massive TSS scores may only happen once or twice a year, so it's more of an exception than a rule. Over winter I was riding about 750 - 850 TSS weeks, but with a lot of MTB that may have been underestimated due to the powercal strap. Awaiting Quarq Quattro to sort that out and plan my CTL better with dual disciplines. If anything with a Powercal it has overestimated it not under.
Sworks20 Posted September 30, 2013 Posted September 30, 2013 For accurate HR TSS use Golden cheetah as it gives you a TRMPS based PMC.
Sworks20 Posted September 30, 2013 Posted September 30, 2013 Zilla: That is the point I am trying to make in an earlier post where I said that the spikes - 2554w in your case are a huge error and all those spikes - regardless of amount of seconds all add up over a ride and therefore throws your average Watts / TSS and IF out. Delete those spikes and your TSS and IF drop. Take those increases over a period and your TSb, CTL and ATL are out considerably. On the strava point the software picks up your PM / Powercal readings and doesnt use its own algerythems to predict the power average on segments. I am in no way saying what you doing is wrong and not that you pushing out those scores weekly as I know you train alot and are committed but when you really know want the most accurate data and analyses there of everything has to be spot on which in most cases peoples arent. As I am sure you know, its not about putting your file into WKO+ and going "Wow I pused 400w for 10min and a score of .976 for a 5 hour ride. that alone is not right before analysing the file(s) Reading some of the scores returned on rides in this thread is a simple tell tale that their data is wrong.
Bianchisti Posted September 30, 2013 Posted September 30, 2013 I think the number is over 400/week for marginal gains. What you mean? Anything less and you just maintaining your shape?
V12man Posted September 30, 2013 Posted September 30, 2013 And what is WKO+???? Aaargh... seriously..... Go and buy and read this book... http://www.amazon.com/gp/product/B007WZ55XI/ref=cm_cr_ryp_prd_ttl_sol_0 Chapter and verse from the horses mouth, so to speak....

V12man Posted October 1, 2013 Posted October 1, 2013 Avg TSS over the past 3 months 1121 Daily, weekly or monthly?
Keithc Posted October 1, 2013 Posted October 1, 2013 Daily, weekly or monthly? Monthly - so got some work to do!!
V12man Posted October 1, 2013 Posted October 1, 2013 Monthly - so got some work to do!! Indeedy.... just check your FTP is correct first... it throws the whole calculation out of whack considerably... Hunter Allen seems to think that a figure of 700 a week is about the minimum to show reasonable gains, and my gut feel is that this is correct, because that is 7 - 10 hours a week's worth of training, and at about that point I personally think I start to get stronger. I would love to have 10 years of power measurement history to verify that - but unfortunately I don't....
Bianchisti Posted October 1, 2013 Posted October 1, 2013 Aaargh... seriously..... Go and buy and read this book... http://www.amazon.co...p_prd_ttl_sol_0 Chapter and verse from the horses mouth, so to speak.... HAhaha! Yeah sorry man, but thanks for the heads up. All this talk and the shortcomings of the PowerCal have me contemplating closing my eyes and bending my credit card on a new PM!
davetapson Posted October 1, 2013 Posted October 1, 2013 My commute is just over 100. Ironically, when I'm unfit and it takes longer, the TSS is about 120 - when I'm fitter and faster it dips below 100. Doesn't seem right that when you are riding harder and faster that your TSS drops.
V12man Posted October 1, 2013 Posted October 1, 2013 HAhaha! Yeah sorry man, but thanks for the heads up. All this talk and the shortcomings of the PowerCal have me contemplating closing my eyes and bending my credit card on a new PM! Buy and read the book first.... then at least you will see what you are missing out on before you bend the card... Alternately buy a good used one... plenty out there - for relatively less.
