his is an exercise just for the purpose of equating everything to the theoretical 100 rated horse to establish some sort of standard time, so if a 50 rated horse is carrying 7 stone, it suggests that his time might be 78lb better than he actually achieved to get a 100 rating, so if its 3.9lb/length to keep it simple, he would have completed 20 lengths sooner and his time would be 4 seconds quicker (20 * 0.2).
Many years ago I was talking to Dave Edwards "TS" and one of the first questions he asked me was "how do you deal with racing weight's carried over 10-0", I replied I have a cutoff top weight limit of 10-0 and a bottom weight of 8-0, so if a flat horse in an amateur race carries 11-6 you weight it as carrying 10-0, he replied correct.
The classic example of this was in an amateur race on Derby day the winner of the race rated higher than the Derby winner due to it carrying something like 11-6, this anomaly happens because racing weights are not linear i.e 1lb does not equal one length.
The most amazing thing about using cutoff weights is it actually works, Dave Edwards was the first to do this.
