Were you a fan of that book "More BASIC betting" that had those programs in BASIC code back in the late 80s? One of them was a program that spit out an odds line based on beaten lengths for horse racing....wondering if that's where you got the idea, as that is the only place I've ever seen that mentioned...
I actually used that code as the basis for my oddsline in the original PaceAdvantage software that I wrote and used way back in the day....
