I think we should start with that and add stuff as we go if needed.

Ah, you mean RES. That's the "resident" part of the memory, i.e. what
the OS decided to keep in physical memory at this point; the rest is
swapped out. Basically, RES is not interesting, only the total
virtual memory of the process (VIRT) is, because that's what is
counted towards the total VM of the system. Although the complication
is that VIRT also includes the so-called "reserved" memory, which is
not necessarily in-use yet.
