You got it !
I would have thought your next question is why on earth is this so difficult ? It comes down to Robinson's purpose in installing the Datcon, which is not to help operators with their billing or pilots with their logbooks, but to keep an indelible track of the engineering life of the machine.
The engineers work this out based on flying hours because that's where the main stresses they worry about occur, rather than loggable or chargable hours which are somewhat subject to the vagaries of legislation and commercial pressure. Therefore the number that goes in the helicopter tech log is the flying time, and hence imho Robinson's change in the 44 range to measure a better proxy for that flying time ie. engine running and collective up.
And yes, in the R44 unless you get the lever all the way down in autorotation (ie solo pilot, minimum weight, or serious updrafts), the Datcon will continue to turn.
