FYI as I migrated to 1.6.2 from 1.6.1 and 1.6.0, my U went up from 4.0 to 4.2 and 4.4 respectively. Great job ck, I am really impressed highly appreciate your efforts (in spite of the persistent curses bug lol).
There is something I find weird in 1.6.1/2 though. Does this E indicator actually make sense? The total E indicator seems to work properly.
