Jay... The alter cup is a one design championship. It contributes nothing to any handicap analysis or system.

You need a race with two different classes of boats.

IF you collected times on the fleet of phantoms... you would then calculate the rating for each helm and notice just how poorly the third place team sailed to its rating. My point... for portsmouth to work... you need A LOT of quality data.

Just for grins... try to get a 2015 list of WL buoy races with a Handicap class
