Your rating is based upon repeated observations.  This is required to form an
ELO number.  But the conditions of each measurement are different.  Different
programs or versions of programs.  Different machines.  The experiment has no
control and the data points are not valid for the conditions of ELO calculations
except as guesses and extrapolation.

In order to calculate ELO, a magical machine opponent that does not exist has
been formed.  It has fought Anand and gone to Dortmund and all sorts of exciting
things.  However, this composite beast is a figment of the imagination because
it does not exist.

All that having been said, if the machine were held constant and the program
held constant so that we actually had something stable to measure, I doubt if
the outcome would change any.
