Yesterday I detected a bug in ZP race data. I finished the Big Spin event in less than 30 minutes and rejoined the event to ride a few more minutes as a warm down (and yeah, to spin the wheel one more time, cause late join as allowed). So technically i finished the same event twice: as a full route for the first time and as a part of route for the second time. And now the data in ZP is a mishmash of two rides: the finishing order and average power values are correct (taken from the first ride) but the values of power for 20, 5, 1 min, 30 and 15s, average and max hr are taken from the second ride (and are totally understated because it was a warm down). The NP value is absent, variability index is <0.
I can notice the same problem among few other riders (I think they rejoined the event too).
I tried to do the same action once again for the bug verification but I haven’t noticed any problems with data for the second time (will try again in a few days).
