crash,

You would only lose if you laid the winners at an average of 22% higher than the tote.

Thats a fair asking even for betfair.... and remember this is only the winners and from my expereience with betfair the tips which are going to win are usually showing no where near the 22% on average. most show around 10%-15%.

But I am not following it, its just an idea put out there for others to use and experiment with as they see fit.

Good Luck.
