This is how i do it.
Dutching quinellas is the same as Dutching a single runner, the lower the odds the less profit/ return, the more over the book, the more cost involved to win a set amount back.

To get an appox return on two runners just add their odds together, its not exact but some times it works in your favour.

You might for example pick only even numbers in a dog race.
2,4,6,8
This is from the 28th June Gosford Dogs race 5.

Add up their odds.
You might like to win a set amount back; $100.00 or you might like to spread a $100.00 across the runners. You will need a dutching formula for all of this just do a search in the forum.
For this exercise we want to win $100.00 plus cover our cost.

Price per runner
2=$3
4=$16
6=$18
8=$7

So.....

Price per Quinella
2,4=$19
2,6=$21
2,8=$10
4,6=$34
4,8=$23
8,6=$25

As it rurned out 4,2 won,paid $32.5 on QTAB
The total cost to win $100.00 = $46
So each set of runners will cost this..

2,4=$7.5
2,6=$7
2,8=$14.5
4,6=$4.5
4,8=$6.5
8,6=$6

As you can see 4,2 won and paid ($32.5 * $7.5= $243.75) -$46 =$197.75
Loads of overs here.
Dont forget you could also use the lowest paying pair as a saver bet.
Really its endless but as with all things punting you gotta pick em and this is where i have discovered that nothing works unless you have a very large and endless bank and if i did i would'nt bother with all of this.
