With the filters added ..... 1st run LOT 37%, 2nd run POT of 31%, 3rd run POT of 12%. The filters, logical ones, turned two of the runs, esp the 3rd run (a LOT of 34%) from a loss to a Profit !!!! I'll have a bit of a fiddle and get back to you. The 1st run showing a LOT is surely on the back of the 2nd to 4th placing at it's last start. What you've proposed here darky is not too dissimilar to my system, and you're showing a POT in at least 2 runs !!
