TheSchmile, I have broken down the prices of the losing lays but unfortunately I can't find anything consistent with them.

Because I only lay the selections on S.P. and not on the exchange, an accident be it a fave or a huge outsider is fortunately a loss of only $33 regardless of price, so I'm not too worried about a blowout if there's a $200 accident, whilst an accident at this price on the exchange might wipe most if not all of the profit, depending on its price. Laying on the exchange the higher the price of the accident then the more is lost.

I would not be surprised that if I had layed the selections on the exchange and not on S.P., the method might not even be in profit, which it currently is. With S.P. the loss is not high but so too the profit is relatively small. It's a trade-off but I think it might be safer to lay outsiders on S.P. than on the exchange.

Fortunately there have not been any accidents today yet, but it can happen when least expected.
