Default Prop slip calculator

What is the numeric number to use for 1.36 to 1 gear ratio?
I am trying to find what my slip numbers were today.

I found all kinds of slip calculators just didn't realize that I was just supposed to enter the 1.36 ratio.
how does 11 percent slip sound with a 4 blade Bravo prop and a prop shaft height 7/8 above the lowest point of the hull?

11 % is not bad at all. IMO but that's just me

when I put the 26 maximus on I was at 8%
Bret from BBlades said that is race boat efficiency - BUT it didn't handle properly with the stock prop.

So what is the proper percentage range that you should be in? I calculated mine and I was at 20%. I am running XR drives with imco shorties and 34 five blades.

I believe15 to 18% is normal for a V bottom.
