In the real world rolling take-offs are the norm and not the exception. Do we no longer train for the real world? If the checklist or SOP requires 10 seconds on the runway, a review is called for. 'Ready' means just that - all checks done and dusted with the possible exception of a couple of minor items that should be committed to memory and easily done on the move e.g. strobes and transponder could surely be memorised by anyone with enough smarts to be flying. What next for the checklist? Throttle open, stick pull back, check houses getting smaller?
As for checking static RPM, isn't that what the run-up bay is used for?
There is already a big thread elsewhere with some good (and not-so-good) advice on how checklists should be developed and used, and indeed whether in single-pilot operations on simple aircraft using basic memonics is not actually safer for pre-takeoff and pre-landing phases of flight.
