If you really want to cut to the chase here it takes a Rotary 3 revs to
go through a cycle. The rotor is geared down 3 to 1 and it takes a
piston engine 2 revs to go through a cycle almost seems like the piston
engine has the advantage.. the piston engine exchanges the swept volume
more often..so you would think it could process more air and fuel.
Another way to look at any way.. maybe just penalize the rotary by 1.33
just for the noise they make.
