if you’re very jr and on reserve, watch out for taking a gs too early in the month. The ‘payback’ may only be that you get a few extra days off in the same month. There may be no real expectation of a banked PB day and also a limited ability to get a subsequent gs to ‘roll’ the pb days since you’ll be last in line for gs #2,#3, etc.

Now if the pb days give you some mid-month days off that you really wanted off but couldn’t get on the initial bid, go for it!
