"Aspro's Melbourne Cup System".

I don't know who Aspro is, but if you google the name you'll find the source. It was made freely available so I don't believe I'm stepping on anyone's toes... Had 4 choices last year, including the eventual 100-1 winner, Prince of Penzance. According to their figures, it's got 38 of the last 53 winners.

Rule 1 List any Cup acceptor placed in either the Caulfield Cup and MacKinnon Stakes
Caulfield Cup: Jameka, Scottish, Exospheric. MacKinnon Stakes: now called the Emirates Stakes and held after the Cup....don't know how that's supposed to work anymore.

Rule 2 List any Cup acceptor placed 2nd, 3rd or 4th in the Moonee Valley Gold Cup
Who Shot Thebarman, Pentathlon, Excess Knowledge

Rule 3 List any acceptor who was placed 1-2-3 in the Melbourne Cup at their last cup run
N/A

Rule 4 List the Lexus Stakes winner
TBD - Nominations extended 'til tomorrow morning but presently include De Little Engine, Pentathlon, Real Love, Rose of Virginia, Tally, The Bandit or Tom Melbourne.

Rule 5 Delete any horse whose last run in the Melbourne Cup was an unplaced run.
Delete - Excess Knowledge (7th 2015), Who Shot Thebarman (11th 2015),

Rule 6 Delete any horse who is aged 3yo or 7yo or older.
Leaves: Jameka, Scottish, Exospheric, Pentathlon (if he makes the final field) and - if they happen to win the Lexus and back up in The Cup - one of De Little Engine, Real Love, Tally, The Bandit or Tom Melbourne
