I’m a fan of the way WKO4 displays the PD records:
As well as being much easier to read visually, it also excludes the ride from the previous PD curve, so that you can actually see how much improvement you’ve made.
I’d echo the thoughts of those who’d like to see a table of discrete times: 5 seconds, 60 seconds, 5 minutes, 20 minutes and 1 hour.
