Too good to call lower?

[TPS2859]

I too would like to know why the signals being properly used not a big deal? I've seen refs use signals that I wonder what book they got them from. Such as the over the back call... they look like a monkey hanging from a branch on the call to the bench. Or how about the "slid the hip over" to indicat a block call. Lots of discussion on looks from shiny shoes to no belted pants as far as profesionalism so how about proper signals.
