So, the main idea is to slide the columns forward so that the number in the last draw row matches the actual last draw. The question becomes how far forward to slide...

Since the most wild per column statistic is variance, there seems like a logical target.

For a pick 3 example, the evening variance on the draw from 3/24 (6-0-5) was...

Column 1 ... 4.8, go back four sixes (or 5 sixes if rounding)

Column 2 ... 6.04, go back 6 zeroes

Column 3 ... 2.22, go back 2 fives

In this way there is a definitive starting point. The decision to use the most significant variance digit or rounding can be back tested. Also, initial exploration does not require any coding, easily tested in a spreadsheet.

The result would be a list of combos to play... and the date to play each. If I were to run the experiment today, it would yield

Last draw from yesterday

One combo for tonight, one for Friday, one for Saturday all the way to Wednesday.

Simply play the number for that indicated date. You win or you lose (or you paper play). That easy!

Maybe the variance is not the best solution, but any hits on this (or any other "system") are purely coincidental at best. Back testing is equally simple, just pick an earlier date and " slide " the data down to see if there was any luck from doing that in the next 7 draws.

Now I chose variance, which is data that I gather from the last 150 draws in my classifier function in my app, you can use any arbitrary source, such as 5 back on every column. (Not 5 rows, the 5th appearance of the last winning number).

If it proves as useless as every other way during the spreadsheet testing phase, then it can die there without ever writing a single line of code. And paper play is always within the budget!
