Reporting box? We don't need no stinking reporting boxes!!!
The manual clearly defines the reporting box. In 3-man I use it a lot b/c most times I have to come table-side after reporting. However in instances where I "report and go back" I don't think I ever make it to the reporting box.
In 2-man I would say I use it about 50% of the time, the 50% being those ocassions in which I am officiating table-side when I have a foul call.
I've gotten away with it so far.
Oh yeah, I forgot. Rec League and military intra-murals, my percentages go down to about 25%.
