Ok, I worked today on making an improvement on OZDOC's spreadsheet.
I decided that one meeting for a month was just not enough.
I think every race meeting going back to the beginning of 2008 should suffice.
I have come up with a way to extract each horse's last 3 starts data from UNItab. It doesnt show 4th or worse just unplaced, but i have been able to put in days since last start, barrier, weight etc.

I am just testing it out now and I will release this when I am happy. All I would like now is some systems to test to see if they are good or not.
