We\'ve thought of making a 5 point shift for the database--adding 5 points, and may do it. JB hasn\'t decided as yet. The problem is that everything in the past--the intro seminar, past races in the archives, TGIs, would have to be changed to reflect the new data points and to a large extent this is not mechanical, but rather a labor-intensive job. It\'s on hold for the time being.
As far as weight adjustment, what you suggest is impractical. There is no such thing as figures unadjusted for weight--weight is INTEGRAL component of the figure calculation. To adjust for today\'s weight might result in a constantly changing listing of what a horse ran (assuming different starting weights). And as OPM points out, overweights occur frequently.
The figure a horse earns reflects the effort it put forth in a race. What it did, it did and it did it carrying whatever weight it carried. No sense changing that. It\'s accurate and that\'s the most important factor. If a horse runs 2s, it runs 2s. Just because a horse earned the 2 carrying 120 and it carries 114 today doesn\'t mean the horse won\'t run a 2 today. It may.
