Ah, now I see. It would have been helpful had I noticed that root symbol 
of yours :-)

So, like Warren, I'm finally convinced, but you could definitely have 
had that easier...

By the way, I find the following way of writing your formula helpful:


Probability of option X winning given that voter V's ballot is drawn :=
1/N + (V's standardized rating of X) / (N-1)sqrt(N)

where "standardized" means the usual thing (expressed rating minus the 
mean of all of voter V's ratings, divided by the standard deviation of 
those ratings, using the usual version of the standard deviation for 
sample data, that is, with denominator N-1).


Yours, Jobst
