I did let the internal algorithm make it's optimization (can't remembere 
which key sequence it was) once everything has settled. The lab here has 
2-3 degC ambient variations over the day, but putting the Thunderbolt in 
a box which is ventilated (well.. fan-ed) by the LH temperature 
controller in a steered way, the temperature variations are down to 
single clicks of the Thunderbolt-internal thermometer reading (which 
appear to be 6 mK).
