Question about calculation of W'

Hello!

I have a quick question about how W’ is calculated. The W’ calculation was observed from the settings tab, which was auto-populated the entire time. Here is the series of events:

Before Jan 12, my stats were as follows

  • 20m FTP = 240 (last 42 days)
  • 3m power ~ 280 (not exact number) (last 42 days)
  • W’ = 14400

On Jan 12, I did Tour de Zwift and my stats are as follows

  • 20m FTP = 248 (last 42 days)
  • 3m power ~ 280 (last 42 days)
  • W’ = 14400

On Jan 13, I did a 3s power effort

  • 20m FTP = 248 (last 42 days)
  • 3m power = 306 (last 42 days)
  • W’ = 15960 (it shows 15960 in the last 42 days in the power tab)

Jan 15, I did TdZ again

  • 20m FTP = 248 (last 42 days)
  • 3m power = 306 (Last 42 days)
  • W’ = 14400 (it still shows 15960 in the last 42 days in the power tab)

Why did it go back down? Is W’ calculated off the latest ride I did instead of last 42 days?

3s ? Or 3min !?
280W for 3s for someone who’s able to hold 240W for 20min, is really odd !

PS: sorry, can’t answer to your question :sweat_smile:
