I'm having a difficult time following the logic in that. I
don't believe that point could ever be reached. It would
require a fast-attack slow-decay copper.
The temperature rise time should be the same as the fall
time. As long as cooling from radiation and air contact
exceeds applied heat you are OK no matter how thick the
copper gets.
