I have not been able to confirm what I am about to tell you and there is a chance that it is a prank.
What I have been told is that if you can put ZO in trick mode and then enter your slalom speed and ABC/123 setting. What you get is a whole new set of slalom settings and if reports are to be believed these settings are very good. I am told at least a few pros like it a lot.
The problem is ZO does not capture the times. I am told that the times/speeds are good but ZO is not programed to capture them. Heck! ZO thinks you are tricking back there.
The disclaimer again. My original source on this is a joker and I have not tried it. The whole idea makes me nervous. I would have tried it out this weekend but I tweaked my shoulder and did not ski. If you try this and the boat flings your sorry ass all the way across the lake it is not my fault.
