10 second average power

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.



Please add 10 second power - it will make the world of difference to many of us.
