Rules for staging?

Not sure about NHRA. IHRA in the Rulebook lists a "Staged Minimum", which I believe is the time a car must be fully staged to trigger the Autostart. It also lists "Staged to Start", I think is the time from when both cars are staged til the Tree activates. Stock and S/S (actually all Sportsman classes from T/D to H/R) have a 0.6 seconds "Staged Mnimum" listed. "Stage to Start" is 0.9 seconds for S/SS.
