	Yeahp ;-) Formula is a little bit complicated (at least to me)
but AFAI understand the threshold will be 0 as soon as variance is.
Also when variance is low enough but not 0, only very low confidence
will really affect the rendering (i.e. be worse).
	I noticed your "almost always" which translates for me to
"it's never perfect" in my previous post :-}
