Anyone with a 36 calculate your prop slip?

I actually went up with the props I ran last year and was talking with Tom at Hydromotive yesterday and he said that 16-18% was not that bad for a true deep vee. He also said that people focus too much on prop slip.
We are working on the hull a little this year and taking the A/C intake off that I know if costing me a lot.
I'm going to also try out a new pair of Hydromotive P5X and see what happens.
What are you getting for numbers?

Mine's not exactly a 36, but I thought it would be fun to post...
I have a 370 Force. Weighing in around 10,000# (including the generator, hot water tank, TV, Microwave, Coffee pot, etc...)
454's at Approx. 525hp
Offshore Performance 23 P 14 1/4" diameter
1.5 Gear ration
5100 RPM at WOT
Theoretical speed is 74 MPH, actual is 61 MPH
Prop slip 18%

I bought a pair of 26p bravo 1's from Baja36ft that have been labbed by throttle up. I tried them, but spun the hub while i was out. I hit 71mph before i spun it, with 6 people and 3/4 tank of gas.
Im getting the heads ported and milled along with a valve job and cometic head gaskets. Im hoping to hit 74, just running some slip numbers to see if it was possible.
