Back in ancient times (the 70's), there was a magazine called The Gambling Times. Those were the days when we went to libraries to search through microfiche race result charts to develop our own speed/class ratings. Young handicappers probably don’t realize that those Beyer, Equibase, Thorograph and Brisnet bold black ratings never existed in the old days. In those days you could frequently get a horse with a 30% - 40% probably of winning at 10 to 1. Normalized speed/class ratings were only available to those who did the work and maintained their data on index cards, computer punch cards or the earliest version of spreadsheets like Visicalc.
Things have changed and overlays are more difficult to secure but following is a link to Horseplayers Monthly. It’s the closest thing I have found to the old Gambling Times, and it’s focused on horse racing. Thought you players might want to tie in and get these publications. Some, not all, of the articles are data based and you might find them helpful or interesting if nothing else. Enjoy.
