i have used them like that for profits.....i usually find races where 3 or 4 horses qualify through all four statitics and box them in exotics. I generally only play races where every horse has had at least two runs. Look for previous form when horses are resuming from spells. The qualifiers for this Saturday are:

Randwick Race 1: 1,2,5,6
Cheltenham Race 1: 2,3,4
Cheltenham Race 5: 1,4,5
