Actually, it would probably be better to require 1 ballot type to have
a mean of 1 and the rest have a mean of zero.

Otherwise, it isn't the same voting system.

My proposal resolves most of those issues, after the votes are case,
each ballot has a probability of p to be excluded from the count.

However, for most of the theorems that that this would depend on, the
variance wouldn't actually matter.  You could set it that the variance
is 1 part in a billion.

This would create the slope to prevent the (meta-stable) equilibria.

Right, it adds a possibility for each vote to affect the result.

OTOH, it is also unrealistic that voters would only care about the outcome.

Most people would prefer a situation where their favourite loses 55-45
than one where they lose 70-30.
