Let's say you manage your PB in 5min and 20min power in May 2024, while you haven't broke those records in 5 previous years. That means you have got stronger (while fitness graph today tells another story based on your training regiment- which is basically totally useless regarding your power numbers).
So, power graph shows your numbers comparing to a previous season of your choice, but what I'm suggesting is a trend graph/ development graph that shows your best power numbers development.
Intervals.icu show kind of the same thing, but comparing to heart rate, which is nice, but a little too complex. Strava could maybe let you choose your development graph comparing to your "how did that ride feel" which we fill out after every ride upload to strava.
