Sorry, no rest for the wicked, get back to work

is that based of all a users ride data for 60 days or does it guess it using some other method?
All activities in a 60 day period as posted elsewhere a few thousand times

This is funny because all I ever see is how light riders are at a disadvantage. So are they at a disadvantage or not? Or is it more of a tipping point where you pass a certain threshold you go from disadvantage to advantage?
TBF we need to get documentation written up for them which I donāt think weāve done yet (or I havenāt seen it yet). I have a meeting with Flint later (he forgot I was on holiday) so Iāll chat with him about it then.
making sure there hadnāt been further changes without us being made aware, we know zwift like to do that sort of thing, I guess I should have asked what sort of time effort is used as there are many different ways of calculating ftp from 3m max efforts to 20m which can give a varying degree of different results
We havenāt made any changes to how the calculations are made otherwise I would have told you.
Itās done on a 2-50 minute power curve.

Also itās CP not FTP, just to keep the terminology super clean!

yeah i thought it was CP based not FTP based
No need to reverse engineer it, the curve calc is super simple and every single example that has come up in the months since it was introduced has been explainable - either by looking at the realities of efforts in that period versus what some thought they had done, or due to an erroneous reading or something like the weight change in your example.
The best, or dare I say only, way to game it, is to do not any max efforts on the entire platform other than in the last 2 minutes of a race.
For anyone that does that, meh. More fool them.

well you have just found out my cunning plan to get around it

I agree with you more or less - my comment was made before the weight change was discovered so at the time I couldnāt understand.
That said, I can go choose all the various power models on intervals.icu to estimate CP and none of them match the number James me gave above. Some of them are a bit below it and some are above it with a variance of 12w. So reverse engineering the calculation can definitely allow someone to game the system if they were dedicated enough. Iām right there with ya on the āmore fool themā comment though.
Iād say a 45kg rider with 5wkg 20min effort riding in & winning B races is definitely not disadvantagedā¦
They have entered 2 of the 3 ZRL races and I think won 2 of them, maybe they placed in the first one rather than won it.
They didnāt ride the TTT as they are probably disadvantaged in that raceā¦
For me, a rider with 5wkg 20min effort riding in B and picking hilly races is getting close to sandbaggers riding down a level to ensure they win or competeā¦ I will add, they are not doing anything wrong and using the system as it is meant to be, so itās not on them to change.
Itās not my arguement to be fair, I raced in that race and didnāt have any issues at the time - I know others commented during the race and itās been brought up here a few days later so itās not sitting right with others.
As I said above, itās quirk of the dynamics and itās not changing any time soon Iād guess, so need to go with it.

WTH? I canāt even spell correctly during a race let alone type. Iām not even sure I have any cognitive skills during a Z5+ effort! 
Oh yeah, very nice implementation of The Banhammer, @Gerrie_Delport_ODZ ! Instant and decisive. I like it.
intervals doesnāt calculate CP in the typical way though - and in fact it uses a single best effort to make things more complex. The High North CP calculator is the best to use as the maths is, imo, probably identical - only Zwift uses more efforts. However, 4 efforts is enough to get an extremely high level of reliability (as indicated in the spreadsheet).
Youāre excused.
This time.

I was to busy being dropped on the KOM to pay attention to the specifics.
I think what got peoples attention was, they rode solo away from the lead group (of about 30) in the lead up to the KOM, bike swap, flew up the climbā¦ this might have irked a few
Yeah, riders pulling off a successful bike swap will tick off the field. If you can get 5 seconds or so before the swap point, youāll only be behind 7 seconds after and you can make that up in about 500 meters on a dirt climb. And then pull out a minute over the rest of the climb. Super annoyingā¦
