Great stuff, guys. This helps a lot.

You make a great point about boats/sailors getting slower. My opinion would be to not increase a handicap based on boats getting less seaworthy and sailors getting Alzheimer's. Unless changes are made to a design/materials, or someone can prove a gross error in calculation of a number (assuming it was based on a large enough data set), I would expect the numbers to be adjusted only to deal with the boats and sailors getting faster.
