Carnegie,

I have done some analysis but can't (or at least without a bit more effort) do all the criterea:
I have done:

1) Only select horses with a winning percentage of 40% or higher the win and 60% or higher the place - Win % only

2) No two or three year old races or restricted class races. - See results breakdown, assume 3yo+ is OK

3) Only select horses that have finished within 4 lengths of the winner at their last start, provided they did not win. - OK

4) Only select horses with a proven first or second up record in similar quality races. - Not done

5) Only select horses that are proven at the track or distance (50% place at worst). - Not done

6) Never select a horse with an apprentice jockey on board unless they are claiming below the minimum (generally these horses fail rules 1 & 3 hence the reason for minimum weight and the claim) - Not done

7) Never select a horse that has drawn off the track. Stick to horses that have drawn barriers 1-7 (unless down the straight at Flemington or Vic Park). - OK except for the exceptions

8) Only bet if the odds for the win are greater than $3.50 - OK

9) In races where there are more than one that suffice the above rules no bet. - Not done

10) 25 units the win 25 units the place. - Can only do win results.
