ATC gives a descent clearance at pilot's discretion whichilot acknowledges. 4 minutes later pilot starts down and reports leaving current altitude. Necessary to make that report? I asked a Chicago center controller. He said that the initial acknowledgement was all that was needed and he didn't need nor even want the second call.
I then asked him if he appreciated a call upon entering holding. He said "no, not when in radar contact" but knew it was in the AIM and then expressed a wish that the AIM would get updated and things like that got deleted.
