So you already were posting film, I'd missed that. If you're going to try hard, try hard but don't pressure yourself over it. Just sponge it all up, info on all things -SA, gunnery, ACM, timing, etc. And just keep practicing. If you can isolate some unknowns you want answers on from everything else in the situation you're having a hard time with, more people will tend to answer.
Try to tune out the smack talk and arguing because at this point it's only going to distract you from what'll really move you up the ladder.
I'll be on tomorrow. Just ask when you see me.
