I would suggest 3 lots of 150 selections .

Then compare the 3 batches.

If one batch shows a strong profit & the other 2 batches , more or less break even , then we have a clearer picture if it has legs or not.

I too have a program.
Used in races with 12+ runners .
It has a 92% success rate.
Its called a RNS program.
This stands for Randon Number Sequencer.

Bet 10% Liability to bank..
