Unfortunately this seems to be occurring relatively frequently and not only reserved to WTRL and TdZ events; I posted something about this in another thread for our JETT event yesterday (zid=1645524) in which some riders have had their data fully/correctly processed while others - including myself - have not.
Traditionally on ZwiftPower - and I’m unsure as of why - power data appears in what I would refer to as three installments: The first is the almost immediate posting of results with just average power and ranking, then the second is when power data initially fills (and is always incorrect, as it is reported lower than actual), and then the third is when data is finalized and the correct metrics appear (20/5/1/30s/15s as well as average and max HR).
However, for yesterday’s aforementioned event, some riders seem to be stuck on that second installment, while others have been fully processed through all three installments. As a reference point, my 1m/30s/15s power for yesterday’s ride was 705w/957w/1048w but ZwiftPower is currently showing it as 384w/390w/396w; obviously a material discrepancy. A couple of weeks ago it happened to me in another event but with much less differentiation, so I thought it might be a one-time thing. However, this is obviously becoming too frequent and widespread over the past few days.
It seems like one debacle after another since Zwift has taken over ZwiftPower (remember the backlog of hundreds of thousands of fit files a few weeks back?)… not to mention the complete lack of transparency in dealing with suspect ride and riders (i.e. reporting someone who is riding at 7w/kg for 20 minutes yet nothing happens). All in all, this is extremely disappointing.
