After spending since May with Sure Path and having it at a dozen tournaments and countless drivers using it at multiple sites there are some things that came to light in regards to this topic
First time users worry more about being down the middle at the expense of the skiers, this probably relates to the Pro's concerns. Some drivers got 'used' to Sure Path and relaxed it became better for everyone, some could not shake the 'down the middle at all costs'
Being towards a skier at each buoy DOES NOT necessarily equate to a good or helpful pull to a skier
Sometimes the skiers relayed the pass felt incredible and a driver "off sided" them once or more even
Sure Path data alone will not make for a better driver, looking at your path after a pass is not enough to analyze what occurred, additional knowledge of what the skier did during the pass helps analyze what occurred and why, where the driver may have erred and why
As drivers we should all strive to be as close to center line as possible, but not at the expense of the skiers. Drivers need to be more educated about their skiers, how/when they pull out, their tendencies through the course etc and tournament organizers need to stop having 3 different drivers for each of the skiers 3 rounds. Same driver, same skiers for all rounds, drivers can learn about the skiers, skiers gain comfort with how the driver drives, makes for better scores
Maybe slightly, maybe a lot off topic, I don't know...stay down the pipe but don't screw the skier
