I guess the Summer to Winter schedule makes a difference to the amount of SBY's but the most impacting factor would be the 200+ cadets that have come on-line for next summers deliveries. The good (even great) news is that after next summer there will only be limited newbies coming on stream due to no new a/c.... YIPEE! Then, as O'Leary would love to see, everyone will be maxed out again hitting nearly 900hrs and there will be no upgrades except for normal attrition etc.
Trust me, he hates to see pilots doing less than 18 hrs work/week!
