I think I've changed my opinion on the stock perfectpass ball settings. I set them all back to stock, and calibrated my baselines yet again, this time trying multiple calibrations as they would vary by 10-20rpm and average them out. No Skier times in the course were mostly 00, with the odd +/-.01 occasionally showing up. Next my wife on Light and myself on Normal spent an afternoon running repeated passes at one official speed lower then our normal passes to get consistency on SG mode (no zbox). We ended up with:
L: 08/35/40
N:10/35/35
Ball times were all good, again with the odd +/-.01
Added back in zbox at B2 and stock setting of 08. Same results.
Zbox at 10/12 - was really standing me up after the ball, couldn't make my hardest pass at all.
Back to zbox at 8, and feels right again.
Pulled a few other(and better) skiers at 34mph on normal into 32'off and boat times are still solid.
I do think that if we were into shorter line skiing, going beyond 32'off that the ball 3 times would start to appear on the slow side with these settings, coming back to my change in opinion that the stock settings are probably pretty bang on for those hard shortline pulls. That's if your baselines are bang on.
I'm beginning to think that the major deviations from stock ball settings and high zbox values are a result of baseline calibrations.
