Horse racing betting and handicapping systems vary a lot in their claims and profitability. There is no doubt that some are based on sound facts discovered from years of study. Most betting systems require patience and if successful provide a reasonable percentage margin of profit. Before using a betting system check the validity of the claims made by the seller. A list of past results of the profitability of the system would be expected. Looking at other systems may also enhance a system of your own. Betting systems can be very simple. A few people for example always bet on the blackest horse in the race and have shown a profit. There may be some truth to a simple system such as this since the color of a horse is carried through in its genes along with its racing ability. The true art of horse racing betting is to find a method of measuring a horse's chance of success using information other than the odds provided. A reliable measurement cross referenced to the odds will find horses which are under valued in the betting market. Things taken into account would include pedigree, weight allowance, distance, age and the betting odds.
