8 from 10 is 10 selections
i think you mean how many bets, its 45 bets at 8 timers and 10 bets at 9 timers and 1 bet on the whole lot.
you'd write the instructions like this
say you are using a ??1 unit stake
45 x ??1 8 fold
10 x ??1 9 fold
1 x ??1 10 fold
so it would cost you ??55
if the selections were an average of 4/6 each, you would win
if all ten won ??135.00 for your ??1 on all ten
??992.30 for your 10 ??1 bets on the 9 fold
??2,679.30 for your 45 ??1 bets on the 8 fold.
if only 9 won you would have ??99.23 for the 9 fold and 9 x ??59.24 for the 8 fold bets.
hope this helps?
i dont normally back so many. try and pick 5 teams at about even money and back them in trebles. 4 timers (4 folds) and a full 5 timer (5 fold or accumilator)
