During the Abingdon programme's final fortnight, they kept referring to "18 years of Central News South".
On the first main evening Birmingham programme after CN South was abolished, Bob Warman welcomed Herefordshire viewers back "after 17 years".
Presumably, the exact number of months that CN South existed was somewhere between 17 and 18 whole years?
I thought that the inconsistency between rounding up / rounding down was a bit naff.
