You do have to set the controller to lower tolerances when you're controlling by liquid temperature reading. I use a 2° spread for liquid in a 3° spread for air/ambient.Years back I posted some traces of temperatures I recorded with some datalogging equipment. Unfortunately those images seem to be gone and I can't find the originals.
As I recall, the cycle times did vary between air temp and immersion or insulated surface temp. But, as one might guess, the liquid temp didn't swing much at all because of the relatively large mass.
Maybe I'll record all that again one day, if for no other reason than just because.
