The method today had 4 selections for 4 smiles for a profit of $39.46.

Out of interest I applied the same rules to non-Maidens.

On Tuesday there were 10 selections for 10 smiles for a profit of $32.
On Wednesday there were 16 selections for 14 smiles for a profit of $4.
Today there have been 13 selections for 11 smiles (2 more races to go) for a current profit of $50.
