I am trying to understand a little more about GS pay. I'd like to take a hypothetical month were the GS trigger is 72 hours, the bank limit is 77 hours, and my line is 74 hours. If I were to pick up a 2 day 10:30 GS that pays 21:00, would I be able to bank any of that time? Assuming the answer is "no", then is there any way other than just straight-pay white slipping above the bank limit to fill up my bank?

edit: as a follow-up (ignore bank aspect for this question, just curious about total pay), what if I only had 70 hours on my line prior to the GS? How many hours would I be paid for the month assuming I didn't have any hours already in the bank to fill up to the GS limit.
