Hey guys!
This discussion has nothing to do with the OP question.
Since we do not use oversquare props, blade stalling is a non-issue here, and a can of worms better left closed. All analogies don't help much in understanding, and just try to explain what happens without exactly knowing what happens. There is good software (free) out there that shows what higher pitched blades mean to prop thrust and prop disk airspeed relations. It certainly is not an analogy with a clogged vacuum cleaner (with a radial pump). That device follows quite a different set of rules.
