Back Judge belt timer

>>NCAA mechanic is to hold hand in air at 10 seconds left mark<<

Isn't that only in situations where the clock isn't visible or is malfunctioned? Also, I know the TASO mechanics list it, but do the CCA mechanics list it as well?

I guess what they should have is two warnings, at 5 and 10, but are different in type.
