Pete,
We found if you stayed on starboard tack all the way to the lay line or even a little past you would be headed at the end of your starboard run but lifted on port when you tacked. The port tack would lift you all the way to the mark with a little header at the end if you tacked early on starboard it seemed like you would sail more of a header on port.
I did this and found that I was getting bad air off the fleet of F18 that would continue on Starbord Spi run rounding the offset.
