Evaluations...

[Scratch85]

NFHS is the opposite of what your evaluator appears to require.

2-whistle or 3-whistle, non-calling officials freeze their field of vision to observe players until the calling official completes reporting and turns to observe players. IOW, everyone maintains their position until the calling official has completed his duties, then the switch is on.

Admittedly, many (me included) freeze, wait for the calling official to get into position and begin reporting and then initiate the switch before the calling official has completed reporting. Keeping players in view at all times.
