Joe,
I have attached a simple spreadsheet that members can use to track stats for your 3 latest filters, just replace the UK results with their own. Maybe an expert Excel Guru could tidy the formula up, it took me quite some time work out how to get the result to just 1 digit.
There is a filter I used to use in Lotwin called Sum of Digits which is similar to the ones that you have produced
example
Draw 02, 19, 29, 38, 39, 43 the SDs for this are 2, 1, 2, 2, 3, 7
so the Sum of Digits for this draw would be 3111 (3x2, 1x2, 1x3, 1x7)
Draw 18, 28, 33, 27, 38, 46 the SDs for this are 9, 1, 6, 9, 2, 1
so the Sum of Digits for this draw would be 2211 (2x9, 2x1, 1x6, 1x7)
Is it possible to create this filter
SDs possible would be
111111
21111
2211
3111
321
