Mattio,
When I forward tested this one I used the "Original "rules as given out.
<1010 M

From TAB 1 down the selection is the 1st horse one comes too that ran 1st LS.

If no 1sts apply the rules to horses thar ran 2nd.

(Although not specifically stated I assumed that meant the run in current campaign)

Thats it.

Result 8/10 lost.

A well deseved winning "LAY" system.

Hope that clears it up for you.
Cheers
