Depends on reserve utilization and whether or not buy up is in play.

If the reserves are utilized as much as the company wants and there is no buy up, they don't care if one cat makes 130 and another makes 60. They could be more even at 110 and 80, but it doesn't matter. The total pay is still the same...But there is more to this argument.

Keeping a significant portion of the lines below 68 or 65 saves money. It keeps the RLG low so utilization doesn't have to get too high to meet their target of credit vs. hrs flown. The company actually is financially encouraged to create excess carryover to keep next month's BLG low. To get BLG low next month they have to take flying out of next month's lines and put it on this month's lines as carryover. You will eventually be paid for it but it does not contribute to BLG in this month the next. Carryover is extra flying not accounted for anywhere but in the individual's pay summary.

This is besides all the volunteer and draft that is saved in the first week by stuffing it with carryover.
