Bill Miller. From the text of your post, can one infer that the formulae is currently being applied, but was not used in the past? Also, it would seem that only WEIGHT is the consideration, and not the weight per horsepower? Is horsepower, or was horsepower ever a consideration for inclusion into IT classes?

Was this formulae that you present fact, or rumor...how factual can we expect the information to be?

This is not ment to be a challenge, just trying to get a handle on the workings of the Great Body of Working Minds in Topeka (?). Sorry if it sounds like one.

Good racing. Bill
