I’m sure someone’s already crunched the numbers wrt the entry fee, purse % to those who finish well enough and what nelson mentioned in #5. So it becomes a decision of whether or not you feel your horse can finish well enough to at least get your money back.
What is FL’s purse distribution percentages? I found this, “In 1975, the state of Florida enacted a purse-distribution format that has had revolutionary implications for the sport of horse racing in the United States: Its adopted plan provided 1% of the purse to all finishers in the race lower than fourth; this meant that the percentages paid out to the horses finishing second, third and fourth (but not first) became variable, depending upon the size of the field. For example, if a race had twelve starters, 60% of the purse went to the winner, 18% to second, 10% to third, 4% to fourth and 1% each to fifth through twelfth; with only six starters the winner received the same 60%, but 20% went to second, 13% to third, 5% to fourth and 1% each to fifth and sixth. This system is still in use at all of the state’s thoroughbred tracks today, although a slight modification in the actual percentages (resulting in the second-place share being increased at the expense of the third and/or fourth) was made in 2005.”
So if you finish in the top 3, with a full field, you make your money back, with a tidy profit in the top 2. At 4th / 4%, you get $480,000. Fees exlcuded.
