I want to back 4 selections in the same race BUT have 2 for savers and the other 2 as plunge runners. For example if I want to outlay 50 units per race and my selections are 4.00 25%, 4.60 22%, 5.00 20%, 6.50 15%, but to outlay 82% is odds on and to outlay greater than 50% is simply crazy. But what if I take the 5.00 20% and 6.50 15% as plunge runners = 35% and only have savers on the 4.60 and 5.00 runners so that if the plunge runners win I am in profit and if the savers win then the outlay of 50 units is returned no profit no loss.

One method of return is to divide the total predetermined outlay of 50 units by the odds of each runner, add these up, then divide this into the 50 unit outlay, giving the ratio to multiply the odds of each runner to bet and returns a profit if any of the 4 win. (is easy to work out on an ordinary calculator but this is NOT WHAT I WANT). I WANT to know how do I calculate 2 for savers with 2 for plunges as in a 50 unit total bet outlay. What is the formula for this and how do I calculate it ?????????
