... as long as you don't stir the air too much when you're reaching for
your sixpack. (;->)

Seriously: the temperature is crucial if you match transistors.
If you read the same Vbe on the meter, but your transistors have
a temperature difference of a few degrees C, you have no matched
transistors.

(Not saying that you don't know how to do it. Just in general,
I wonder how many "hand matched transitors" are really matched.)
