Of course, that had been running for a while so restarted and had another look with nothing having been done since restart other than start a terminal.
Went through the process on all the releases (only Debian on this machine) and came up with some results:

With 8GB I have plenty of RAM and a ridiculously big Swap file on the SSD, so it's not causing any problem but I'm curious as to why so high.
Any ideas?
