There's a big difference b/t doing good research and putting together a punting paper/mag like the Sportsman/Wizard or Best Bests and selling it for $4 or $5, and putting together a system which is advertised to pick lots of high priced winners and selling it for $10,000.

Selling tips for $33/tip is also just as questionable, given as propun pointed out a punter would have to outlay $330/bet to expect to break even on a LT basis.

There's an old saying "Those who can - do, those who can't - teach"

While some ex-sportsman go on to be coaches etc - the best sportsman usually ain't the best teachers and the best coaches ain't the best sportsman.

In racing its "Those who can find winners back them, those who can't sell systems"
