One more thing...Vacation. It should be a solid 7 days blocked out in PBS and valued at 3.5 hours/day just like TSA.

You would then have 18 days off. If you worked 12 days with those being 3, 4-day trips, the average credit would need to be 17 per trip. At 70 hours per diem per trip that would be a little over 4 hour per day credit. TSA has a 4.25 min day. So see how they solved the same issues Mesa has? Just duplicate them in this area. Trip rig would be better for commuters however. Min day they can start you early day one and finish you late day 4. Trip rig would be 70 hours per 4 day with the math above. Hence Trip rig is better IMO.
