Got it! Reducing the zip range doesn't work but going the opposite direction does.

Rule 1. TABs 11, 12, 13, 14.
Rule 2. Only those EXACTLY four kilos from the zip star.

In my sample, 146 bets. Win = $345.50. Place = $173.30.

ALL the good winners are in this sub-category. And if we remove the megawinners the results are still healthy:

144 bets. Win = $182.60. Place = $145.80.

But longest run of outs still equals 21.But if places pays or breaks even this could be broken up with place bets where longest run of outs is 12.

By these figures, a megawinner now and then would be the icing on the cake, not the salvation of the system.

Quite a few in this category tommorow.

Rosehill - R7 #12 Conzeal.
Moonee V. - R3 #13 Yallah Limit, R7 #11 Star Doc, R8 #12 Monde Special.
Eagle Farm - R5 #Flighting and #13 Janneke
Vic Park - R5 #12 Spar, R7 #12 Street Parlour.

Sandown on Sunday - R6 #13 Keltic Verse, R8 #12 Yakama.

Thanks for all contributions and suggestions. Much appreciated.
