Oh, no problem, I got the point alright. I'm quite familiar with the
Heisenberg Uncertainty Principle, and it's misapplications. You still
don't seem to understand that a smear of T-stick crayon is NOT "changing
the system" in any real way for our purposes. Please correct me if I'm
wrong.

I'm surprised you've used the exact word to describe the phenomenon. I
wonder if you understand the implications. And I'd agree with your very
last clause, "or less". I'd say way less. Infinitesimally less.

OK, whatever. Then you might want to consider using a heat-shield. That
might help you some.

QED, Bernie.
