@sbusquirrel LOL -- I understand. If it helps any, the people I know in the system for Secret and TS are coming in right around the marks @marko.hakamaa provided above. I think nearly spot on for Secret and slightly shorter (30-40 days) for TS. Both are for uncomplicated investigations (from what they told me and seemingly the life they have led from what I know).
So, I think it's calendar days, but to be honest, I have not seen in written in stone yet. That is why I asked.
