A minor correction to this. The 4:30/day is not above MPG as the starting point. Rather, it is a credit added to your current earned line value. In your example if you have a 76 MPG and you get within 4:30 of it, say 72 hours of pay credit, then you call to "pay me or release me," and the 4:30/day then gets added to your pay credit, starting at 72 hours. It will certainly go above the 76 MPG, but it doesn't start there.

"25.11.G.10. If a Reserve Pilot's credit value is within four hours and thirty minutes (4:30) of his MPG, the Company may elect to release him for any or all of his scheduled Reserve Days in the remainder of the bid period (with no adjustment in MPG), except that the Reserve Pilot will not be released for a single day, other than his last day, without his consent. A Reserve Pilot whose credit value is within four hours and thirty minutes (4:30) of his MPG who has not previously been notified regarding release from remaining scheduled Reserve Days must contact Crew Scheduling on the day prior to each of his scheduled Reserve blocks no later than 0900 LBT to determine whether he has been released. Should he not be released, he will receive four hours and thirty minutes (4:30) credit, times the scheduled Reserve Days in the remainder of that scheduled Reserve block from which he is not released, or the total actual credit time, including Deadhead, flown on those days, whichever is greater."
