Here's a question for you handicap whizes. I understand the portsmouth numbers are adjustments for time. You take your elapse time, multiply it by 100 and divide it by your portsmouth rating (hence the lower the rating the lower the divisor and more time is added to your elapse time). BTW, the Thistle is the scratch boat in this system, having a portsmouth number of 100. This is a straight percentage thing; if my rating is 5% lower than another boat's, I have to beat that boat by better than 5% on time to win.

My question: How is PHRF rated and is there any feasible way to convert from one to another? I've heard of "minutes per mile" but don't understand what that means.
