I also got the impression that it started "suddenly", as you say - but
just a couple of weeks ago.  OTOH that isn't supported too well by the
numbers my Python script spat at me :-/

Yes.

The ones above are, admittedly, not representative: more commonly I'm
seeing delays of around 3--5 minutes, as the graph shows.

Hmm.  In the last month, I see some messages with <2min, and a handful
<3min.  On the other hand, I also see several (just) above 10min.

Okay, I'm curious: why is Octave good but gnuplot bad?  Do you have a
better alternative to suggest?
