Hey there, so this is certainly in the category of “edge case”, but worth documenting anyway. Intra-day changes in eFTP appear to be triggered differently than Seasonal power PBs, and this can result in the wrong (lower) eFTP going forward. Basically eFTP changes appear to always be in comparison to yesterday’s eFTP, ignoring any eFTP changes earlier “today”. In comparison, seasonal power PBs are determined in comparison to all earlier activities (seasonal records), including activities earlier in the day.
Steps to reproduce:
- Record an activity that calculates an increase in eFTP. Example 250W to 260W > email notification and performance chart are updated saying new FTP is 260W
- Record another activity in the same day that calculates an increase in eFTP above 250W, but less than the first, say 255W > email notification and performance chart are updated saying new FTP is 255W
Expected result
eFTP change is not triggered on second event because 255W is less than 260W from first activity
This happens even if it is the same model parameter fit point that nudges (eg it happened for me based when the long-duration fit point changed twice)
