If the board was before April you will have no chance at all.In Snake's defense, I got picked up from the Spring 2019 board and was thinking the same thing.
Totally get where you're coming from with the Year Group spot though.
Since I meet several of the PA's requirements for advanced placement, I might poke around and ask about it. If I share my intentions to accelerate my training/qualification pipeline, might be a decent justification.
Even if it's just to O2E, it's 18 months, which could be another look at higher rank on the back end of your service. Could also be the difference between 3 years at O6 for retirement rank multiplier and 2 years at O6 and one year at O5.
Can't hurt to ask, worst they can do is say "NO!"
