Couple of questions...

On the Fab56 I was on this morning I noticed on approach to the last stop it said the usual "Next stop, New Bridge St" but also added "where this bus terminates". I really approve of this and have noticed it on other services but not the Fab56 before. Is this a recent tweak or have I just never noticed it on Fab56s?

On the way home on an Angel21 this afternoon the NSAs were announcing the bus stops we'd just left as the next stop. It did this as we left Newgate St Wilkinsons, & High Level Bridge North.
A week or two ago I noticed a Citylink57 making announcements much later on than usual. (The next stop was being announced as we were pulling up at it).
How does this delay develop sometimes? I could understand if its a drop in signal at a certain point/time, but to then carry on with the following announcements being delayed too seems odd - I'd have thought it'd catch up after the next stop?
