PP time is within tolerance, r set at 150, skier wt 165, crew wt about 50 low. Skier complains speed seemed fast. So close to tolerance PP says speed 30 rpm too high. So, I lower r to 100. Next run he complains speed is too slow. PP says to increase rpm by 25. So, I set the r to 125, PP says 0 adjustment, skier is happy. How much difference is there with a whole 30 rpm adjustment?

Another friend's 2005 Natique PP was never calibrated. After I drove it, commented he might want to calibrate the PP, it was calling for 450 RPM adjustment!

the 450 rpm adjustment indicates his magnet pu in the boat is on the drivers side of the boat, most course's are set up with the magnetic pickup to be on the passenger side. You can guess how I learned this. Of course I was in a friends boat.

What version is this? You may want to check calibration of the system by running both directions... with no skier, just crew weight and see what you get. Is the course equipped with magnets or are you using the hand timer? Did the skier make all the balls or stop pulling after missing one? Without a fall button or magnets on all 6 you can get some crazy numbers.

Assuming you have a 13" pitch prop and 0% prop slip (and you probably have 5-10%) 30 rpm = 0.37mph

Unless your skier's first name is Andy or Chris, I doubt he can notice this.

That's what I thought, but he did call it correctly

It's a brand new Nautique, can't imagine they screwed up.

Any dealer any manufacture can screw up, proved on this board. All you do is move it to the other side usally running the wire through the bow seating area.
