For accurate HR TSS use Golden cheetah as it gives you a TRMPS based PMC.
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.
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.
I don't always train with the power meter, so weekly TSS scores are misleading, but I normally average about 130 - 170 in a 1hr 35 min odd ride with 550m of climb.
How hard are you riding during this ride? Reason I ask is that is you hammer it the score is more, if you cruise it the score is less so to return that score for every ride of that "route" would be incorrect. You can return a score of 80 for that aswell.
You need an ACCURATE FTP measure first - not sure how you go about doing that test with a Powercal though.. but you can definitely do it - because you can use heart rate as a measure to reflect Normalised Power (NP) but that still assumes you know your HR at defined power levels - the powercal is built around that concept that HR relates to power produced.
By definition a TSS score of 100 is the same as 1 hour at FTP - so 1.5 hours at FTP would give you a TSS of 150, and half an hour at FTP a score of 50 - similarly - 1 hour at 50 % of FTP gives you a score of 50, and 2 hours at 50% of FTP gives a score of 100.
Get the FTP wrong and TSS is out by the same factor that FTP is out.
If you have WKO+ and a Powercal do a 20min all out effort and upload the file. Play with the ftp setting and if you return a score of 35 tss your ftp for the powercal is basically correct but will be different if you have any proper power meter.
Powercals return incorrect values though due to heart rate spikes and that increases your power spikes so unless you clean up the file and remove the huge spikes the scores are wrong.
I'm about the same as you if not less, ave 550- 600 tss.
Some weeks this year though Ive had 1200-2500
1200 is possible, 2500 is hard to believe unless you doing 30-40 hour weeks.

just looking with the eye it seems to be around 0.850 / ride
Your FTP is wrong or you racing every time you ride your bike. .850 / ride is not correct. Have you got rides of .9 or 1? If so, change your FTP. Your readings are false.
I never did this event but 9/10 people said they really did not enjoy it and will not be back due to many reasons but they all mentioned how wrong can an organiser get their route profiles wrong?
The 10th person I spoke to never finished and went home and rode in Lebanon for 2 days instead.
Laps are really quick cause the course is on Strava 
Impressive to see Matthew Beers and Derrin Smith give some Pro's the back wheel. These 2 guys are showing some serious potential.
Yes I have noticed you cant take anything personally on here and I ride road and mountain bike.
Just wanted to say hello to the people of the hub. I have been reading for about a year in the background and thought I would open a account today.

weekly tss score

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.
