True for dial-set Compurs, as you say. The recco to not change speeds on a cocked shutter was related to the high speed helper spring more than microscopic wear on the speed ring. Interesting point: Zeiss lenses on Hasselblad are ALWAYS speed changed on cocked shutter. Are they stupid or misleading us with erroneous engineering so we wear them out fast and have to buy replacements every 6 months?
