Might be a bit less confusing if they at least added the original air dates, like they do with Take The High Road.

Using seemingly illogical series and episode numbers that presumably only existed for internal production reasons at the time doesn't really make much sense, it's making it hard to navigate through things. The series lengths aren't even consistent- they vary from 30 (series 10 in 1986) to 51 (series 51 in 1999 and 58 in 2000) episodes.
