Having recently lost my A cat status due to not hitting more than 5.1 w/kg for 5 minutes for 3 months, I decided to correct this by aiming for a 5 min PB at the start of a race this afternoon.
I aimed for 400-420 for exactly 5 minutes, and at 5:00 my average was 408.
This 408w was displayed on the race summary screen after the race, and in the companion app.
However, in my Zwift.com account, my new 3 month 5 minute PB is just 396w, a difference of 12 watts, which is enough to confine me to B, as Zwift also has my zMap at 393, 15 watts less than I can demonstrably do for 5 minutes, which makes no sense.
Zwift Power has this 5 minutes recorded as 380w. This is 28w less than Zwift says I did.
So, same 5 minutes, same event, same platform, yet we have a range of 28 watts (380, 396 and 408)
Over 5 minutes a difference of 28w is massive. 12w is not insignificat either.
Anyone know what is happening?
Itâs annoying to ride 5 mins at âpain effortâ, reach the number you know you needed for the purpose of that effort, then see that you didnât achieve what you thought you had achieved.
wondering if it has to do with the start pens, you know how the timer doesnât start for a few seconds as you leave the start pens⌠maybe those few seconds arenât being captured?
On Zwiftpower you have the green bolt as you have all your data set to private. ZP therefore cannot access the fit file so it uses very coarse data. Maybe this is the issue with the Zwift website too, I donât know.
According to Gemini âset your Zwift activity privacy to Public in the Companion appâ. Iâve never toggled this setting so I donât know where it is.
Itâs best to make all data public or people will assume you are cheating.
