Not that I have made a study of this, but I started commuting from
Waterloo to the Wharf 4 months before Christmas, and most of that time
was jostling to get on the train, reasonably often having to wait for the
next one. Since January, no jostling, never had to wait for the next train
and probably could've got a seat a couple of times if that sort of thing
bothered me.

That sounds like a huge improvement. I tried boarding at London Bridge
around 08:00 a few times for the Wharf but could not get on the first
two or three trains that arrived, back in 2004/5. So I used the DLR from
Bank instead, which was quite civilised by comparison.
