Well, at least now i know what you folks at the pointy end of the fleet(s) talk about.

Back in the middle-DFL group, we ponder such questions as:

"how did that spinnaker get launched upside down (BK)"
"Why is the C-gate over there?"
"the bunny goes out the hole, around the tree, and back down?"

But, should a handicap system base their numbers on the theoretical perfect race for each design? In which case polars (both wind and sea-state) would be the only real data. Actual race data factors in human performance which varies widely.
