Be careful of the ************** $100 a day plan. It is a loss chaser based on something as simple as dutching all horses from second favourite out until you can no longer achieve a 100% profit if one of them wins.

Each target is $10 so 10 completions are required per day to get your $100. You don't have to be Einstein to work out that 4 or 5 favourites or a mix of favourites and roughies in succession can lead to big outlays just to get the $10 ahead.

As for staking on placegetters, I think parlaying or rolling all-ups are a good way to accelerate profits if the strike rate is high and there is a flat stakes profit. If you are reasonable with excel you can write your own program - don't pay someone hundreds and hundreds to do it for you.
