"moot" means "already decided."

As in, "this question has already been answered", not as in "I've decided this question isn't worth asking."

Worst answer is probably to ask the FSDO. The FSDO where you ask might not have the same answer as the FSDO where you land. And even if it's the same FSDO, the Inspector you ask might not have the same answer as the Inspector you answer to down the line.

I agree with you completely on the "it's not worth .3 on a close question" although others might say, "who the heck's gonna worry about .3".
