Mr Sanford - I thank you for your comment and whilst I don't doubt that you may have had many discussions with Mr Robinson regarding low RRPM recovery I wasn't quoting the R22 manual but rather the R22 Safety Awareness video in which he specifically states the actions must be simultaneous. If you would like me to quote the manual then I in turn refer you to Safety Notice SN-10 which says, in part:
"No matter what causes the low rotor RPM, the pilot must first roll on
throttle and lower the collective simultaneously to recover RPM before
investigating the problem. It must be a conditioned reflex."
Rgds.
