Where is the error in "C/S, passing 3,200, climbing to FL90"? That is required in the US to verify the Mode C report on the radar. Has been since the '70s.
Question for ATCOs, do you expect a report when actually leaving a level/altitude when you have issued a "when ready" (US: pilot's discretion) clearance? The US AIM requires it in Chap 5, I think, as mandatory report.
