Vic,
Yeah, I have the same concerns. I think it's going to come in somewhere around 800. I think one difference might be this is a cut specifically for deep downwind sailing, not for reaching, so it's bigger than it otherwise would be. Here's how Don from Pineapple put it:
"In 20 knots true wind, if you're sailing downwind at 10 knots of boat speed, the breeze on your sail is more like 10 knots. So, yes, a bigger sail will sail downwind better than a small one. The big sail would be less happy to sail true wind angles of 90 or less in 20 knots, but in 10 knots you'd be sailing around at high angles like 50-60 degrees. Tight reaching.
If your goal is sailing 150-160 apparent wind angles in no more than 20 knots, then you're going to want the bigger sail. If you get caught needing to sail higher angles then you can reach with your main & jib. If you want to crush across the bay from Sausalito to Pier 39 in 20 knots then you may want the smaller kite."
