Well, that's rarely a good yardstick for anything.
With the hours flown and the number of helicopters operating daily I would say it’s the global yardstick. Both good and bad.
Many regulators have made it a legal requirement to have a pilot at the controls when the blades are turning, for good reason.
Best practice and safest option always.
My company has ops specs approved by the regulators to allow pilot to exit the aircraft with blades turning. Just normal part of our operation. Always the pilots personal decision when to and when not too.
