Could you borow a prop of known pitch to re- test?
Yeah if it were ali I'd say that was a safe bet since they are cheap and brittle so people rarely modify them. But its stainless and might have been modified for racing or other purposes.
I agree on finding another prop of known pitch to test and/or marking the fly wheel and trying to eyeball the ratio.
