In plain English
- The months range means: USCIS finished 80% of its recent N-400 cases at this office within that time. It's a reference point — some cases finish sooner, some later.
- "Case inquiry possible…" means: if USCIS received your case on or before that date, your wait is already longer than normal and you can officially ask USCIS about it (it's called an e-Request, and it's free).
