Is the technology better? From the information I've gathered on- andoffline, I think not. It seems to me that the system is based on aninput that can't be sampled rapidly enough (GPS) so they addedband-aids to cover the gaps in speed data - theaccelerometers. Then the algorithm is reactive (thus the gassing - Ithink it's an adaptation of automotive cruise control) and highlyovergained. The A/B/C settings can obviously alter that a bit. I'm a bit skeptical about the virtual timing concept but over thatdistance the satellites should get it right as long as the course isright. Even if it has to call for more gas in the second segment, a laStarGazer! It just might suck from the handle, that's all! In the end I think that if I were to design a speed control systemfor skiing, it would end up being a lot like Perfect Pass classic - analgorithm designed around a ski course, not an adapted automotivealgorithm. GPS would only be used to establish an RPM baseline on theway to the course but upon entering the course, GPS-based feedbackwould shut off and the boat would control around it's RPM baseline.Thus the convenience of ZO and the pull of PP classic. I thinkRPM-based (or maybe even torque-based) speed control is far superior in concept than GPS-basedcontrol.    Disclaimers/other random points: 1. There is no such thing as constant speed unless you're at a cablepark. There is always error in the system, it's just a matter of howthat error is managed and corrected. BTW, what's the best known slalomscore at a cable park? 2. If any data I am using to form my opinion is in fact wrong, I've just wasted a lot of keystrokes and some of your time! 3. If we continue down the ZO path, towboat speed control could becomethe defining factor in ski design and technique. Is that a good thing?Maybe it's always been that way? Seems to me that for ZO you want a skiand technique that gets you all of your angle at the ball becauseyou're not going to make up any time/space behind the boat any more. 4. I have only one tournament set behind ZO and it was terrible... Butit was terrible before I got gassed by the control system. I'm nothaving a good year and I'm definitely not blaming it on the system. Isuck behind good old PP classic this year. 5. I do powertrain controls for a living so while I may be a hack onthe water, I have a pretty good idea of what's going on under thedoghouse. 6. I've been waiting quite a while for the right opportunity to saythat I think ZO is a piece of crap and I think I finally found one.
