I just need to play with mine some more.

walked into that one!
I went out solo yesterday and really flattened the head of the sail with about 4 inches of downhaul- like board flat... any flatter and it would.. well... still be flat. Decent wind, not excessive- maybe 7-8ish or so. Huge difference (surprise) when I let off the downhaul and was able to really tell the difference.
Still not sure I am getting the distance though. I need to pay more attention (paying attention to driving, then trying to sheet in the main really tight to get more downhaul, then windvaning into the wind, then driving backwards for a minute, then forgetting to look again) but afer those 4 inches or so from completely slack to "can't get anymore no matter how hard I pull" i barely come down to 8 on the scale (10 at top). And I didn't put the stickers on there either.
