Not sure that is a significant enough aperture to notice it. Those things,
variance and confidence, might have to be more extreme too. Trying to think
of what the default for variance is... 1/128? Yes, is. I've used variance
1/500 and confidence 0.9999 before, I know, and I think it does make a
difference. But not much from between around those numbers you have there
probably. A kind of exponential change maybe?
