Horse racing place betting percentages

For those of you considering a career in place betting, here are the sort of numbers you would have to return to stay ahead of the game.

Dividends / 100 bets	Average Dividend	Units profit / 100 bets
50	2.30	15
55	2.10	16.5
60	1.90	14
65	1.80	17
70	1.60	12
75	1.50	12.5
80	1.40	12
90	1.30	17

In other words, if the average place dividend of your selections is $1.50, you have to have a success rate of 75% on your bets to return a 12.5% profit on turnover in the long term.

So the burning question is, can you maintain a 75% strike rate?
