Hi Ted:

Assuming Park's number is from a standard Ampex timer, then it is head 
hours, and more precisely, guide engagement hours.  Obviously the head is 
running in wind and standby modes, but by having the timer activated with 
the guide, only actual head-wear hours are accumulated.  AFAIK, that is the 
way all quads are set up.
