Here is two ideas.

Last race of quad.

Before the jump check out unitab quad payout figure.

If the horse is fav for race but not lowest quad div back
If horse is lowest quad div n not fav lay

Example

Sunday Pakenham Race 8

Heat blast was paying lowest dividend on unitab for the race quad dividend.
Our Emily mia was fav but higher quad div.

Either back or lay to your preference.

Nr was the same. Fav not lowest quad div. Unplaced

Prepare to lay qr6 h6 today

Another lay method

Lets see if I can lay 14 runners tonight in the Quad leg of Cranbourne

ER 5 - 3,5,9
ER 6 - 2,5,9
ER 7 - 5,7,10,11
ER 8 - 7,9,11,12

This last leg thing looks like it may have........legs.

But what happened with the last 3 races out at Crannie tonight? It was abandoned but I wonder why?
