How to read this
Implied at the off is the average chance the final pre-off price gave these runners. If a group wins about as often as that, the market had already priced the move in; following it would have gained nothing before commission. A persistent positive difference would suggest the final price still underrated them.
Moves are measured in probability terms from 10 minutes out to the scheduled off, for runners priced 30.0 or shorter at 10 minutes. Samples are small at first and grow every race day, so treat single-digit differences with caution. This is research, not a betting system.
