While looking at the new my.zwift.com UI, I’ve noticed that the power graph doesn’t tie up with what I saw in game or Strava.
End ride screenshot - 1019W on first spike:
Strava - peak 1002W on second spike:
New UI - 993W on the first spike (same as Companion):
I don’t know what the reason it. Maybe in-game is instantaneoud peak, Strava is 3 second peak, and Companion is 5 second peak?
