I think you'll find the formula dated to the time when most people said "I really need my total memory address space to be n megabytes, but I can only possibly afford n/3 megabytes of RAM, so I have to just make do with 2n/3 being on a relatively slow hard disk."
This certainly applied when I maxed out my first PC, a 486/33 with 8MB RAM back in 1993 [1]. Just being able to run 16MB of RAM+swap using SLS [2] was heaven. I could have allocated more swap but I could only afford a 210MB hard disk (and I reckon adding any more swap would have been pretty much been counter-productive.). Regards, Martin [1] For those of you into Linux nostalgia, I actually posted a question on one of the NNTP newsgroups on how to share my Linux swap space with Windows 3.1.

A default FC install still uses the 2x formula so I guess there must still be some relevance. -- Howard.
