Isnt the easiest thing to get national to rule on something. Have to run through chain of command to get it to the national level and depends completely on their decision on if it goes up the chain or not. About 3 months ago I posted an obstruction play on a large umpire forum and got over a thousand responses, many of them also UIC's with completely opposite rulings. I contacted both the state USA uic and the state NFHS rules interpreter to ask to have the play kicked up the chain to national for rulings. Both responded with their rulings, which by the way were completely opposite of each other, but as yet I have seen nothing about the play being sent on to national for a ruling.
I seem to remember a few years ago there was an option on the USA rules and clarifications page where you could submit questions for possible review in future editions, but when I looked recently there no longer appears to be that option.
I agree 100%, it really gets frustrating in trying to find the CORRECT ANSWER I would bet if I sent the same scenario to the 1/2 dozen listed UIC's on their web page that I would get different answers
