Ranks of abstract interpretation rules (for TIOBE quality indicator) needed.

[EndlessStorm1]

Hello all,
I need for my bachelor thesis about code improvement, the abstract interpretation from my sample software for the TIOBE quality indicator.
If I have seen this correctly, I can get this property with Spotbugs.
Is it correct that I need all NP_ - checks for this?

If this is correct, I have been able to find 36 rules (all with NP_. However, I can't find any information about the ranks in any documentation.
There are ranks concern to scariest and I could find in my sample software 8 bugs on the rank scary (the information I found in the XML).

Can you tell me if these are all the needed rules I need for the abstract interpretation for the TIOBE quality indicator?

And a list with the possible ranks of the rules would be perfect, so I can determine the compliance factor.
Alternatively, I just calculate all 36 rules as rank scary.

Thanks for your help :)
