I preferred the old “Bests” chart for PR’s than the new one as it was simple and easy to track a limited number of durations. Knowing my 17:22 PR is pretty useless to me, but maybe having that sort of detail is useful to some people. I no longer even look at PR’s where before I could quickly see the last date and workout I set a specific PR on and if I was feeling up for it have that in mind to try an top it in my workout.
