I am not sure what you mean by "DT2 strength 10." I did not see that information in the linked page that you provided. Am I supposed to click on one of the links within BPIP to see DT2 strength?
It seems that I have heard of the concept of DT strength before, but I cannot really remember what it means.
Hover your mouse above "DT2" on BPIP. Or see
https://bitcointalk.org/index.php?action=trust;dt, where it shows "TMAN (10)".
DT strength is the number of DT1 inclusions minus DT1 exclusions, which means it's a measure for how many users are needed to toggle a user's DT-status.
