I said upfront that it wasn't my model *g*. Nevertheless, the
following axioms make it, if not a neccessarily exact measure
of S/N, at least well-ordered:
- You can't lose XP for having one of your articles moderated
upward, and you can't gain from having one moderated downward.
- You can't gain (or lose) more than one XP for each point of moderation applied.
Thus, we can at the very least use the sum total of all the
moderations of all of a user's articles as an upper bound
for the amplitude of "signal", and still compute an S/N ratio
based on the value of that bound -- think of it as a "Peak S/N Ratio"
within the space of all the possible values "signal" could take on
for a given user.
