I'll respond in depth to the rest later but this caught my eye. Little known fact but the Lead actually is supposed to count closely guarded in their area.

NFHS Mechanics Manual 5.3.2-B-1 "Officials are responsible for a silent and visible five-second closely guarded (within 6 feet) count within their primary coverage area."

Unlike the NCAA-M manual which splits the closely guarded count between the Trail and Slot officials, the NFHS makes no such distinction.
