PR is just a notation required because iCrew cant display X days that start at times other than midnight. The PR is actually included in the PB day that you have in the 24 hours before the end of the PR. For example if you have one PB followed by a PR that ends at 0400, you actually have one PB "day" that goes from 0401 the day before until 0400. If that day is interrupted by one minute you get a new PB day, but you don't get double credit for the PB and PR.

The scheduling alert from a while ago gave several examples.
