Here's how I figure the finish and margins will be as the animals cross the line for SHEPPARTON Race 8 this morning.
And also are Prices based on those finishing margins.

5 HARRY HAULAGE 0 $2.1
1 GUITAR HERO 2.6 $7.2
3 JIMMY DOUGLAS 2.9 $8.5
2 SPRING TO EXCEL 3.4 $10.6
6 BOOTMAKER 4.3 $16
8 PUMPKIN EYES 4.8 $20
4 MIRACLE MERC 5.2 $25
9 BLACK GUN BOY 7.1 $60

And going on this information, it seems unfortunately that this race has nothing that suggests there will be an OVERLAY.
That is the major problem I have because I spend ages going over a Race and feel that the time spent must be rewarded by having a bet.

The only possible bet would be an EXACTA of HARRY HAULAGE to beat numbers 1,2,3 but only if these animals are OVERLAYS.
