Number elimination

[Len]

Hi Frank
Many thanks for explaining that Mate, it's much appreciated!
I'm looking at a similar way to yours,
Please see attached txt file.
I divide the numbers into blocks of thirteen
if you look at the ten blocks you will see
27,34,37,45,47,49 missed last time.

So are due anytime now?

Your way looks a lot better to me,
as it home's in on the numbers them selve's.
My way I'm just looking at numbers that miss,
or top numbers over so many draws.
