does anyone out there know the formula for using two runners for saver bets.
I have three runners i want to back. I want to put $10 on the first runner with the other two runners to cover the ten dollars and also cover them self's.

Hope that makes sense.

Hey Gd4th !

I'm just new to this forum and am enjoying being part of it.

Not much of a tippster though...the forum curse you see...haha

Not sure how to explain the formula in words but I have it on a spread-sheet and glad to share it if you would like me to send it to you? It works up to 4 selections in any one race.

bye !

I am not familiar with hotmail. Does that mean that you will post a hotmail address for me to send it to you?

bye !

Just use percentages.
useing you example of $10 with 3 runners at thses prices the first 2 are saver bets
$3.00 = 33.33%
$5.00 = 20%

to get there percetanges just divide thier price by 100 example 100/3.00=33.33
to work out your bets put 33.33% of your $10 on your first selection thats about $3.50
20% of your $10 on your second selection thats $2.00
thats leaves $4.50 for your main selection
this will work on more runners as long as the percentages are under 100

Sorry i miss read your post to get the $10 on your main selects useing above prices just double them....it is always easier to work out the saver bets first and then see what you have left over....just remember that the main bet needs to return enought to cover your savers

not sure if this is any help
go to the ppd site and you can download a calculator that will let you bet up to five horses per race it's free

Not sure if anyone had given you the answer you needed so here is the formula:

I'll denote capital X the amount you bet on horse X and little x the dividend (not odds) of that horse.

Let A = amount on horse A
Let B & C be the horses you want to save on and b and c their respective dividends.

Then B = (A * c) / ((b*c)-b-c)
And C = (A * b) / ((b*c)-b-c)

Now I'll apply this to a situation where you put $100 on Horse A, Horse B has dividend $10 and Horse C has dividend $6.

Amount on B = (100 * 6) / ((60)-10-6)
= 600 / 44
= $13.64 rounded

Amount on C = (100 * 10) / ((60)-10-6)
= 1000 / 44
= $22.73 rounded

So the total outlay is $136.37 and the return if B wins is $136.40 and if C wins $136.38. The difference between the outlay and return is due to rounding.

I hope this helps.

Thanks Racefan
I came up with this, Works the same.

A=runner one $10 to win
B=saver odds 3.5
C=saver odds 4.8


=48 / 2.5 * 3.8 -1
=48 / 8.5
B= $5.6
So do the same for C saver and that should =$4.1

$10 win on A
$5.6 on B saver
$4.1 on C saver
Return B = $19.6
Return C = $19.6
If either B,C wins they cover each other and also covers A at $9.9
Almost at Ten dollars close enough for me.
