I didn't read pages 4 and 5 to see if it was mentioned, but the PBE does have a grace period - once. If it's the first time they've retired and they revoke it within 24 hours, they don't lose any TPE. Unretire after 24 hours but before 7 days passed/creating a new player, you take a 15% penalty. Retire & Unretire a 2nd time, 15% penalty no matter what. 3rd retirement is permanent.
