Heres a place staking plan that I came accross, that capitalises on a good run & pulls back on a bad run.

Bet 1/9th of bank , up & down on remainder of bank.
Bet 1/5th of bank after a placegetter is struck.
Bet 1/7th of bank after a loss
Bet 1/9th of bank after another loss.

It seems to work well if one has a 70% SR.

One method of selecting Placegetters that has its good days is...
Target races with 12 & less runners.
Target all the horses paying $5.00 & less for the win.
Target the hoses from this group that has the strogest UniTAB rating
e.g. take 100pts over 98pts.
Bet this for a place if it is paying $1.40+ ,no bet race if selection is less than this.

One has to have patience if one wishes to take on this approach.

It works just as well on Dogs & Trots.

Check out some past results before betting any real money with this.

Cheers.
