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.
