I thought I would re-introduce this interesting plan which is still performing well at level stakes.
With no form study.

Best using Betfair Fav & prices.
Their prices are far superior to the TABs.

To repeat the rules.
.Wait for a Fav to win before we commence betting the Fav for that venue at level stakes for a max of 4 races only for that venue.

.Stop betting once we have struck a winner at that venue within 4 bets.

.If we strike 4 losers in a row at that venue, no more betting at that venue for the day.

.Now do the same for all the other venues, 7 days a week .

Cheers.
