Thanks, Mark. And three of my "all green" races were not from these venues, so maybe it's quite common. And maybe that's the reason my Lay The Field methods are doing so well.

But I think its raises a few questions:

Is this Lay anomaly common in England?

Is this because there's more "laying" than "backing" money or vice-versa?

Does the market even-out so that it often is less than 100%, otherwise backers are being disadvantaged?


I wonder how many punters are aware of this. It would be inconceivable that Betfair isn't, so hopefully the S.P. market won't/can't be adjusted.
