I have been using Zwift with a Stupid trainer since the beginning of May; I’m having great fun using Zwift. So this week I purchased a 4iiii power meter for my bike. Previously Zwift created the live power we all see on the screen and now the 4iiii is doing it. I am finding the live data I see on screen for power to be fluctuating quite a lot usually 20-40 watts sometime more. It came to some training stars not being achieved because of it 
My HR and cadence are pretty constant but the live power not… I’ve uploaded two graphs which have been created by Garmin Connect. Any tips and what I am missing?
