Working Backwards to Figure Average Payoff

[NormanTD]

If you want to work backwards to figure an average payoff based on number of races, win percentage and roi would you go:

Number of Races x Win Percentage x Percent ROI?

Say you have

29 races
27.5 percent winners
24.83 percent ROI
should compute out to an average payoff of $14.40

This is 29 races x $2 per race x 24.83 percent roi (29 x 2 x .2483) = $14.40

Would the average odds then be:

Average Payoff - $2 / 2?

(14.40 - 2) / 2 = 6.2?

If your $1 ROI is 1.2483, and your hit rate is 27.5%, then your digital odds are 4.539. That's 3.539:1 in traditional tote odds. 3.5:1, dood, not 6.2. You're way off, honeybunch.

If you bet $2.00 on each of 29 races ($58.00) and had a total positive return on investment of 24.83%, you received back $58 x 1.2483, or $72.40 in mutuel payouts. That $72.40 is divided among your 27.5% winners. 27.5% of 29 races is 8. $72.40 total payout divided by 8 winners equals a $9.05 average mutuel, or average odds of just over 7-2 (3.525 - 1), as rokitman indicated (slight difference (3.525 versus 3.539) because I rounded the total payout figure down from $72.4014 to $72.40).

Well, that's why I was asking for help.
