The scenario, 2 props one a 3 blade and one a 4 blade. Both props have the same pitch and diameter and through hub. That said what would the RPM drop be going to a 4 blade?

Yes. Usually 1 size smaller for same rpm as 3 blade. I'm pretty sure of it anyway
I don’t think there is a direct comparison. Typically a comparable 4 blade prop will have less diameter than its 3 blade counterpart. The shape of the blades will be different, the design criteria are different.
It’s like comparing a low-rolling resistance fuel economy tire to a super swamper - but stipulating that both tires be the same size. It’s not a valid comparison...
