Icewynd / Frank,

Yes I sometimes use skips similar to Icewynd, but I use 1 instead of his (0) for a repeat, I use groups 1-3 (0-2), 4-8 (3-7) and >=9 (>=8). This is similar to the first column of "History Segments" in Expert Lotto.

The lines that Frank kindly worked on for me represent the skips for the last 19 draws of the UK Thunderball in skip order.

Thanks to Frank's work I can use a "skip repeat table" amongst other stats to look at overdue possibilities. As you can see from the answer column, a repeat of 1 skip has repeated 4 consecutive times, the average for a repeat of 1 is every 2 draws for the last 900 draws.

So the last skips for the UK Thunderbal were: 3,5,10,13,18 - for the next draw this represents numbers 3;14,26,35 - 5;10,28,34 - 10;3,27, 13;2,11 & there are no numbers that have a skip of 18.

So I am proposing that a single match of 1 for any 1 of the above 4 number groups is unlikely to happen. Using a Group Filter in the above program to achieve this I can reject 261,566 of the 575757 possible lines (5/39 w/o bonus), roughly 45%.

Similarly I can use this with another overdue filter concerning "Decade Groups", Units, Tens, Twenties & Thirties.

Examples of the Decade Group Filter are:

3011 - 3 Units, 0 Tens, 1 Twenty & 1 Thirty

0212 - 0 Units, 2 Tens, 1 Twenty & 2 Thirties

A "repeat table" for this filter shows that a repeat of 2 is very overdue, the last Decade Group distribution for the UK Thunderball was 1211, so I propose to accept lines that have only 2 of the previous Group,eg, 1121, 2210, 0311 etc. This reduces the 575,757 lines to 289,950, a reduction of around 50%.

I know it's a big ask for both filters to hit the same week but we have to have some hope sometimes, these 2 filters used together leave 158,823 from the initial 575757 lines a reduction of around 72%.

There are many filters like this, but they only happen now and again, that's why I keep so many spreadsheets and stats. Hopefully, my theory is correct.

Anyway, thanks to you both for replying, my previous posts didn't spark much conversation even though 185 people downloaded 1 file and 32 downloaded the other. As someone said in a previous post somewhere, there are too many lurkers and not enough posters.

But to the people who do post and help each other, I wish success and maybe a big win.

Incidentally, I realised during this post, that if it's a long one, draft in Notebook first.
