 From your analysis up to this point, I think you know the answer. You must 
be fishing for some poor sap to give you the wrong answer so that you can 
ban him/her to Fremantle Prison.

Don't forget about reciprocity. At f/22, each pop doesn't allow many 
photons to hit the emulsion. So I would think in terms of 16 pops (2x 
normal) in order to get enough light inertia into the emulsion.
