Here’s a wee request for those of you who view punting as an interesting mathematical exercise (as I do).

In the Forum “worst system ever” I showed that it is possible to make a profit (24th April 2017 - 8th June 2017, 318 bets, profit $1,097 on $11 lay bets) without using form.

The only site we can place lay bets is, of course, Betfair where you’re at the mercy of the market. That in itself isn’t a problem as long as one knows what the market differential is. $15 on the TAB translates into a BF Lay price in excess of $20 and frequently higher which imposes a degree of nastiness on one’s wallet.

Has anyone got a database of results which includes BOTH TAB Prices and the comparable Betfair SP/Lay prices?

Happy to “contribute” for a good database of at least one year data.
