That's the smart way to do it... then no tuning of an aftermarket unit for sensitivity control.

Have you by chance had the opportunity to tune ignition on the dyno when the counter is registering hits? To eliminate phantom knock (engine noise) that may be falsely registered as true knock, you would need to use a dyno to locate MBT. If it's true knock then you would see the MBT plateau with no drop in power as a small amount of advance is removed from that area of the ignition reference table.
