I also believe there are many systems that show yearly profits.

One could put the lot up here, but very few would ever follow them.

The first thing most punters would do, is change the rules, then say, that system of yours does not work.

I believe most punters can make 1.5% a day if they had the discipline to stop ,but very few can stop , that's why they will continue to lose.

Here's a Lay system that shows a profit every day.
RULES
Target TAB No.2 for every race.

Horse's Trainer must have a 7% or less win strike rate.

Bet .5% of bank flat stakes no recovery.

8+ runners.

Price 4.00-99.00

Stop for the day once 1.5% profit is made.
