Thanks Bhagwan

This'll test my Excel skills for sure! Appreciate you giving this some thought - will run the numbers this weekend and see how I go and report back.

I reworked my ratings formulas to accommodate lower class races this week (Cl1-6 at country/provincials) - got 5/7 quinellas and 3/7 trifectas at Rockhampton yesterday based on boxing my top 4 rated - 6/7 winners as well - joy lasted about 1 minute when I saw the returns.......still, I enjoyed that minute immensly, considered giving up the day job, island in the sun etc etc....all good fun.

Cheers
