I would like a mode that would show me the critical power graph you can see after you finish your ride during the ride. I often like to compete against myself and if I could see how close I am to setting a watts record for any specific given time period, that would greatly motivate me to put in a little extra effort to do that.
For example, sometimes I am trying to put out the most watts over a 2-hour period and it would be interesting to see how close I am to that record for myself on Zwift… Or sometimes maybe I just want to see my best time for a short 1:45 or mid range 6:30 push.
Being able to toggle this up in the background will help motivate me as I get tired towards the end of whatever time period I am pushing for.
