Projected SP for racing

It's the amounts backing at Sp vs the amounts laying at sp and also taking into account any money queuing in the market that can be matched against during the reconcillation process.

IMO its a bit fishy in noticed a lot of horses that lead over fences return shorter on BFSP than you'd think. Just makes me think the cut off isn't where it should be. Haven't studied it thoroughly but noticed many examples.

The prices reconcile at the point the market goes in-play, so I'm not sure what you're suggesting?  Gruss shows the final value instantly.  If horses are returning shorter than you'd think, it's because more people are backing them than laying.

fair enough - if you say you see the values instantly then guess its above board. I was just intrigued that front runners over fences seemed to be less % advantage over bookmaker SP than others. Made me think the cut off might be a couple secs late but could be coincidence or people looking more carefully at how they line up.

Happens all the time, racingguru. The suspension at the off is always subject to a delay because of the delayed feed. Track players consistently get the chance to lay slow starters before the suspend button is pressed. Have a look at the Betfair SP of the SC Williams fav at Chelmsford ,which had to be ridden along at the start to try to get a lead. Went from about 2.3/2.4 at what would have been the actual off time to a Betfair SP of 2.7

Here it is:
3.0 Chelmsford Vejovis Betfair SP 2.62/Industry SP 1.91.

Most of that drift to the Betfair SP occurred in the final second before the suspension, i.e. AFTER the start, owing to the approx. 2-second delay on the SIS pictures used by Betfair.

I thought they used track Reps to off at the exact time?

only for the bigger meetings gubberbaird

Watch the prices of horses as the horses are circling 10-30 seconds before the off in a jumps race, and watch the jockeys' body language. That's what many on here make money from, and it all affects the SP considerably.
