Hi wesmip1
Are you still doing the BAT thing.

Crash reading back your posts I relise you are talking about SP price , I am backing the IAS Fav at the jump. The IAS fav and betfair are normally the same unless one gets backed in late.
I don't take to much notice of the tabs as they very greatly. eg the last at belmont today Lord Baumay 4.2 IAS opened at 4's on S/tab $5.1 at the jump equal Fav with Gamatron $5.1 on IAS Gamatron 8/1 Gamatron ended up Fav paying $5 on S/tab (you could have got $9 on betfair)

Crash you may want to google the grey horse bot
