Between 2% and 5% of punters make a living out of this caper.

The return to punters from TAB's or the bookies is for arguments sake, say 85%.

So, you only have to narrow the gap between 85% and North of 100% to be in front. Wrong ..... Incorrect assumption. Included in the 85% are those punters who make their living off the punt. They could quite conceivably be taking 20% of the 85% which leaves the unwashed to fight over 65%.

How much money would be on successful stable information in each race ???

So mow you have to be better than Joe Public by greater than 50% just to break even.
