Spreading the loss looks like an interesting idea, but i still don't like trying to make a set profit.

Using this type of selection process and following runners you are going to back your fair share of 20-1 and above runners and a number of these will win and since this whole idea is based around finding that winning run i would hate to have only a small portion of money on it when it wins.

You are better off working out what funds you need to follow a particular horse, this will then decide the bank you need to follow your stable runners and as money becomes available via winning selections you can add more runners or increase the stakes on new runners added to the stable.

If you wanted to employ an idea like the loss sharing you could add each weeks new selections to a new pool, week 1 might have 4 runners week 2 might have 7 runners and so on.
