OK, partial credit, heck you were less than 10% off!
As to prop rotation, that's a good question, and If I told you I'd have to hunt you down and, well you know the rest
Actually, if I could remember, I'd be happy to tell you. We ran both rotations during the year with different prop combinations, as each combination performed a little different. Top end was the same no matter, but the boat ride and turning ability were better in different scenarios.
I promise to look during our first race at Miami in April, (and remember), and let you know.
Take care,
Steve
