Horse Racing Betting Odds

Is this a good horse racing betting system?
1. looking possibilities of the board and find out who is 1 two betting favorites in any other career. 2. If option 2 is likely 3-1 or more, and every other horse is 4 / 1 or higher to be the only favorite to win (with independence of probabilities). 3. if the election is less than 2 ยบ 3-1 not bet this race 4. if the election is 3 or less likely 3-1 not bet this race. Just wondering if anyone has used this system or what people think of this system?
Well ... # 4. If the election 3 or less likely is 3-1, not bet. No # 3 and take care of it? If 3-1 is 3 or less, 2nd choice must be 3.1 or less well, right? It seems as if only bets if a horse is a big favorite, and after taking the favorite to win. I hope not take long to get to this strategy. I'm sure many people who know nothing about racing "Umm? Not know anything, so I bet the favorite, no matter the odds" have used the same technique. The logic would say that is not good, but I can not speak from experience here.
