"It's about minimising your variables."
Absolutely, in general.
But if your sidechannel signal is undetectable because it's hidden in the noise of the real EMC world outside the cleanroom despite the CE and FCC compliance marks, does the "security research" fall apart too, or do they only need an electrically clean environment once, to read the key, and the rest follows automagically?
