But perhaps each postie now delivers more items than before?

Not to my household. I currently get an average of about two letters a
day [I don't count their 'three a day' junk mail flyer allocation].

Back in the day I'd have got about a dozen, several of which were
usefully actioned later that day, rather than the following day [it's
difficult to have a day-job and also pick up your daily post from the
doormat much after about 8am].

I don't mean more letters per property, but more items delivered in total
per shift.

If the letters are spread thinner per household, I don't see how that
could be the case.
