Question Concerning "About" Distances...

[lueylump]

This is a general question about using pacelines run at "about" as compared to "absolute" distances. In the days of Synthesis (less than two weeksago), I had serious reservations when using about distances in my paceline selection because they can distort the E/L Difference graph and possibly effect other ratings.

Two distances that really caused trouble in my handicapping is the about 7 furlong dirt distance at Keeneland (which tranlates too early) and the about 6 1/2 furlong turf distance at Santa Anita (which does not match up well with the 6 furlong turf distance at Hollywood Park or absolute dirt distances). A lot of other tracks also have about distances including Fair Grounds, Louisiana Downs, Tampa Bay Downs, Gulfstream Park, Turf Paradise, Arlington Park, and Suffolk Downs.

So the question is this: Based upon your experience with RDSS does about distances translate accurately when evaluated against absolute distances? And if so, are there still some tracks and distances that one should exclude when making wagercapping decisions because of its propensity for distortion?
