@jeidmann Yeah, I got that... And yes, I think thats going to be tough to determine. As mentioned, maybe the best way is while watching a skier, listen to the engine. TWBC was showing ZO settings for each skier in their latest broadcasts, including swiss. Most were A, I can't remember if more were 1,2 or 3. Another variable I recently thought of is line length. With a longer line the skier connects pretty tight out of the ball, causing the boat to slow down closer to coming off the ball, it will recover and complete its compensation sooner and release sooner. Where a short line doesn't really load until the boat has advanced and the skier has moved more toward center line so the whole process is later. I think the best thing to do is experiment with different settings and go with what feels better, and you feel you ski better. I'm not consistent enough to feel like I can really determine how an external factor is effecting my skiing right now, so I just stick with B2.
