the problem with no stat counters is, none of us are there either. You can say that one guy's punches are harder, but you can't actually qunatify the amount or line that determines significant. From a TV screen I can say yes or no, and it is probably different from the judges table.
The stat counters, if can be a consolidated number among like ten different people ringside and plus tv and reliable is a useful tool. How much damage a person takes from significance is not quantifiable. The whole thing is still all over the place to me.
PUmmeling Arlovski with Volume seems entirely significant where as Mark Hunt it wouldn't be.
