Chrome,

Where do you get tote Figures ?

also here were my prices for non-sp fixed odds on betfair:

TotalMarketPercentageBet=0.63
TotalMarketPercentageLay=1.11

1. ACTION DASHER = 29.0 / 7.8
2. COUNTRY KISSIN CHICK = 32.0 / 9.2
3. RIATA SPECIAL = 46.0 / 19.5
4. KL WAGON MASTER = 3.8 / 3.6
5. TWISTER IN THREE D = 46.0 / 20.0
6. THATSA FIRE CHICK = 85.0 / 21.0
7. CHAMPIONS LEAGUE = 38.0 / 11.5
8. RUN DJ RUN = 48.0 / 16.0
9. KOOL KUE COUNTRY = 5.4 / 4.5
10. FULL BATTLE RATTLE = 80.0 / 13.0

Looks like SP Figures end up somewhere in between the 1.11 and 0.63

How do you know how much to lay each runner for liability wioth SP as it can fluctuate ?
