No, I realize the point.  It really would be not much different to take the
wins+.5times draws and divide by dollars, but that way it does not take the
quality of your opponent into consideration.  ELO calculations find the actual
ability.  Of course with a short tournament, the variability will be quite high.
 On the other hand, since ELO is not linear, the really expensive machines would
be more heavily penalized.
