No, I smooth the load distribution for the calculation, but by no 
stretch of hallucination is the distribution uniform or anywhere near it.

The smoothed loads, yes certainly. I no longer doubt that you wouldn't.

Yes I do, at least for myself, and did before I asked.

That's been pounded into the ground quite adequately, thank you. I disagree.

I'm obviously not going to get anything specific enough to make a point, 
or even a comparison, so I'll withdraw from the land of creative 
science, surprise revelations, and endless repetitions of the same 
opinion and await tomorrow's zombie attack.
