1. Take the lowest numbered last start winner, all races, any races.
2. Eliminate any rank outsiders but leave long shots with even a slim chance.
3. Eliminate all TAB number 1's.
4. Bet level stakes to win.

Strike rate 21%
POT = 6%

Places gets to break even.

Better still, eliminate all TAB numbers 1, 2, 3. Lower strike rate, less action, better POT. Also shows small but steady POT on places.

Or, bet to win by TAB number, so $4 for TAB 4 etc. Assumes that the lower the TAB the better the return, on average. (Actually i added the wrong columns in the spread sheet to find....) Yields 13% POT.

But everything depends on rule 2. distinguishing between a no-hoper and a slim chance.
