Really need a 10 second average power; Especially for workout mode.
I have a stage power meter that can jump +/- 75W from one instantaneous reading to the next. Stages says this is normal (arghhh). 3 sec averaging reduces this to +/- 30W but I can get it down to +/-10W on my garmin with 10sec averaging.
Really need to have it on zwift to be able to use Stages power meter in workout mode.
