Slow Pitch Senior Ball - Judging 12'

[Linknblue]

I have always given the benefit of the doubt on high pitches to the batter. If I think there was a question on legal/illegal at the peak my choice is to always call an illegal pitch. Of course I've got my fellow seniors (who know it all because they are seniors) telling me I don't know what 12' is. Conveniently, most of them are the guys that pitch and push the limits of 12' to 13, 14 and 15'.

The question I have is: What, in your minds (ooh scary thought) do you use to tell you what the limit is? Do you look at the pitcher and double his height? Do you pick something in the background to gauge height? Do you use the brim of your hat and everything that goes above the brim is illegal? What do most of you use?

It might be a silly question but when I tell the guys it's "judgement" their reply is my judgment is off of course. I'd like to have something somewhat definitive to argue my point, if there is anything definitive.

Thanks
