AngryPixie, you mention multiple selections.

I've been experimenting in certain races where I lay not just multiple selections but the entire field on S.P. I've been showing a profit on all my evolving methods with this type of laying, but was not entirely satisfied with any of them. However I've fine-tuned my current method and am currently showing a POT of 22%, and with four more races to go it is virtually impossible to lose today.

If anyone's interested, I select certain races and use certain settings on the neurals to identify horses that are in single figures in my neural market. These I lay for a fixed liability, and all the remaining horses in the race for a higher liability.

What I particularly like about this is that I can put the lay-bets as soon as the neurals load the scratchings. About 80-90% of the selections end up in the black, and quite often the worst accident will be very low. I've even had an äll green race and often very close to it.
