This is an *equation* for crying out loud. Not an experiment. You do not
have to "try" anything. You just plug the number into the equation. The
temperature is inversely proportional to the emissivity number. The close
to zero, the higher the calculated temperature. They have it set to 1 which
gives you the lowest possible calculated temperature.

Nothing can produce a lower temperature per unit of emissivity than a black
body. Grey would be better than black, not worse.

It cannot be more conservative than e=1. You do not understand arithmetic.
