That "rule" still applies - if less than 2 seconds, reduce the iron
temperature, if longer than 3 seconds, increase it.
A lot will depend on the size and heat mass of the soldering tip more so
than the recovery time of the iron. A quick recovery is fine, but is
not the whole story.

I would respectfully disagree with this advice. It is dependent on the
type of iron you're using. The Hakko FX-951 behaves quite different
from the traditional temperature controlled stations. It has very fast
thermal recovery, so typical through hole pads will flow in much less
than 3 seconds, but not because the iron is too hot.

It should wick out completely onto the solder pad and the component
lead in 2 to 3 seconds. If it takes longer than that the iron is too
cold, if shorter, the iron is too hot.
