These figures have been known to be deeply flawed for decades. The larger figure on the left represents the number of fifths of a second the horse ran in contrast to the track record. The track records are sometimes created by freakishly fast conditions & on such days you may have two new records set on the same day by ordinary horses. The track record for a mile at a track may have been set by a Grade One winner shipping in to get a check. At the same track the record for a mile and a sixteenth may have been set by a $5000 claimer having a good day. So a horse that runs a second slower at each distance will get a 95. All things being equal the horse that ran the 95 mile ran faster.
All thing are not equal, which brings us to the daily variant figure to the right. This is an average of the number of 5ths in relation to the track record on a given day. This tends to say more about the quality of the horses running that day then the actual daily variant. On a Saturday, typically better horses run & will run faster the horses carded for Monday even if the track conditions are the same. Using this method the Saturday horses figures are downgraded & the Monday horses are upgraded.
Needless to say these figures are not comparable from track to track.
The sane thing to do is ignore these antiquated figures & use the bold faced Beyer on your left.
