If there is "a simplified way of making 100 buks a day" guaranteed then that same method could make $1000, $5,000 and $10,000 a day. And more. All that would be necessary is the tote pools are deep enough and/or the bookies are prepared to accept your bets.

Now you can easily see the flawed logic of any method that is marketed guaranteeing an income of $100 a day. Make it $100 a day because it is not a large amount and so for marketing purposes it seems believable. People probably wouldn't believe it even if it was just $1000 a day.
