Just finished a race and I note that ZwiftPower hasn’t recorded my 20 minute power.
I finished the race in 20:03 (yes, I know it’s only 3 seconds) so I was wondering is there specific time over 20 minutes that has to have elapsed before ZwiftPower records? Maybe it doesn’t count the lead-in?
I’ve raced for ~20:30 twice in 8 lap crit city races and got a 20 minute power for each. I know that doesn’t help the OP directly but refutes the idea it has to be 21mins
The winner of the faster of the two (bizarrely the Cat B race where I was 7th not the Cat A race I won - that’s a whole other subject) was 20:26 and had 20 minute power
