Do I have this right?

since on a duo core system, /proc/cpuinfo reports both cores and a bogomips number for each, that number is the
value for a core.  Thus 'in theory' the bogomips for the unit is the sum of the two values (the same in every duo
core I have seen)
practically i would say this value is hmm useless

is it hardcoded in the CPU?
is it measured?

if it is measured at which moment of time
which stepping had the CPU at the moment :-)

I realize it is rather relative, but it helps me keep my various systems classified, like system 1 is probably twice the speed of system 2 (given same # of cores and memory).

So I use it only for classification.  Not for any "Great Expectations".
