Not sure who posted it so i can't give credit but here is a way for you to test a system manuly

1. First sample = 150 recent races (or bets) If this shows miserable results, forget it. If it gets near to break even or pays POT continue. This sample will include at least one period of three consequitive days.

2. Second sample = 100 races from the same season in previous years (not recent races) but with NO consequitive days. If its near to break even or in POT, continue.

3. Third sample = 100 random races from all seasons trying only one or two races per day from here and there. If its near to break even or in POT, continue. A system MUST pass this test. (If you only sample consequitive days you can hit distorting cycles and mini-cycles. You have to sample against this phenomenon.)

4. Fourth Sample = carefully tabulate results over the last week's races, going back over some days covered in sample 1 but writing it up on a spreadsheet to examine results more closely.
