Hey @James_Hodges_KRT and @S_ticky_KRT, I have found another interesting case in which Zwiftpower does not seem to calculate the FTP as one would expect. My script which simulates Zwiftpower FTP calculation has been pretty accurate in giving identical results, but today a new situation was found in which Zwiftpower gives a surprising result:
For some reason in this rider profile (ZwiftID=905145) the November 15th, 2022 TeamTimeTrial effort is not used for the FTP estimation. As I mentioned in some posts above, I would have expected Zwiftpower to only use races towards FTP estimation, but Zwiftpower uses group rides etc. as well for FTP estimation.
However, could it be that Zwiftpower is not using plain Team Time Trials for FTP Estimation? To be precise: if events only have TYPE_TEAM_TIME_TRIAL tag in the event settings AND there is no TYPE_RACE tag; are those being overlooked by Zwiftpower? So, when TYPE_RACE is not set, is Zwiftpower including activities which are Group Rides and at the same time excluding Team Time Trials for FTP estimation?
If my above guess is not correct: do you have any idea what other reason could explain why the November 15th activity is not used to calculate the estimated FTP?
