Hello newbie.
I'm having a shocking run regarding selections,but have the solution for your framing market.
You have your dogs in order of margins or times.
I work my markets out on predicted margin from the expected winner.
Don Scott said to use lengths or kilos,but with dogs you can use lengths or times.
Always start by giving your predicted winner 100 points.
At a length behind the winner,the selection gets 66 points.
In greyhounds there are 16 lengths to a second.So a length is 1/16th of a second or .067 seconds.
With mucking around with numbers,every .01 of a second you think the dog will finish behind your top selection,decreases the points alotted by 6%
So if you think the dog will finish .13 seconds behind your top rated selection,It gets 45 points.
The formula is 100 multiplied by 0.94 to the power of margin in hundredths of a second.
So in this example,0.94^13 is equal to 0.45.
And 0.45 times 100 equals 45.
Do this for all dogs,then add up the eight totals.
Divide the dogs rating into the total and you now have the minimum the dog needs to pay on the tote to be a betting opportunity.
It's easy once you know.
If you are still interested but haven't quite understood,please ask.
