The way you do the sevenths is when you're wanting x/7 to start with the xth highest digit in the sequence. For example, with 3/7 I want to start with the 3rd digit number in the sequence which is the 4, so the sequence goes like this:

3/7 = 0.42857142857142857... and so on.

For 6/7 we would look for the 6th highest digit in the sequence (7) and start there:

6/7 = 0.7142857142857... and so on.

For the sake of completeness, here are the first six digits of all of the sevenths:

1/7 = 0.142857...
2/7 = 0.285714...
3/7 = 0.428571...
4/7 = 0.571428...
5/7 = 0.714285...
6/7 = 0.857142...
For sevenths and fourteenth's, notice: 7 x 14 = 98, which is almost 100. So...

1/7 is about 14%, and
1/14 is about 7%

Since these are touchdown numbers, American football fans shouldn't have much trouble with poker table estimates:

2/7 ~ 28%
3/7 ~ 42%, etc

Same for 14ths:

1/14 ~ 7%
3/14 ~ 21%
5/14 ~ 35%

No offense, spoon, but I would rather have my eyelids torn off than learn your way with 7ths

BTW, this method is easy enough to actually do it at the poker table which is NOT the point of the thread, I know. So, sorry spoon, for screwin' that part up.
