They need to keep the SAM....and thus the BLGs...DOWN!!
The best way they've found to accomplish this is to increase the # of hard lines (...reducing BLG avgs)....which decreases the # of "published" reserve lines. (check out the union data re: line allocation by percentage in the SIG notes)
...they then hold off to see how much reserve is eaten away by training, vacation, etc during the conflict/input window.
Any deficiency is then picked up by VTO lines consisting of mixed or pure reserve (...a reserve "shock absorber", if you will).
The union has noticed this trend for months ---- but it seems to be getting worse.
Any guesses on what the SAM will be for June?
Some rumors out there that it may actually be above 68 hrs.
