Hi,
Your tables are not very well organized which makes them hard to read and check. And there is the mistake. E.g Rule 4 is same as Rule 12. So let me show you how to make things a lot more organized, and how you won't do doubles nor miss something.
When there is n columns (Username, Password etc) with only T/F options, there's always 2^n choices for those. That's in this case 2^4 = 16. So to be a bit more organized with this you always start from the top. And then half of those options are T and half of those options F. And you want to put them in that order. So the from the first step:
Username Password Email City Case 1 T Case 2 T Case 3 T Case 4 T Case 5 T Case 6 T Case 7 T Case 8 T Case 9 F Case 10 F Case 11 F Case 12 F Case 13 F Case 14 F Case 15 F Case 16 F Then we go to the next column. Now again you should be as organized as possible to not to miss anything. So again using 'half' rule. At the second column half of the first columns T's must be T and another half F. Same with F column. So The result is:
Username Password Email City Case 1 T T Case 2 T T Case 3 T T Case 4 T T Case 5 T F Case 6 T F Case 7 T F Case 8 T F Case 9 F T Case 10 F T Case 11 F T Case 12 F T Case 13 F F Case 14 F F Case 15 F F Case 16 F F You apply same kind of rules for last columns. Now you can easily see if all cases are applied or not.
Username Password Email City Case 1 T T T T Case 2 T T T F Case 3 T T F T Case 4 T T F F Case 5 T F T T Case 6 T F T F Case 7 T F F T Case 8 T F F F Case 9 F T T T Case 10 F T T F Case 11 F T F T Case 12 F T F F Case 13 F F T T Case 14 F F T F Case 15 F F F T Case 16 F F F F Hopefully this helps you. Always remember: If there is 2 options, you handle 2^x series.

Thanks a lot Teemu.
I have one more question related to this. However I have posted that in a new separate discussion.
