Not sure what you mean by “full-blown calorimetry”, but I can tell you this 
(having been assisting Alan rather closely for the last 
several months).

Typically Alan would first characterize the GlowStick Cell by inserting a 
thermocouple dead center, on the active side with a dummy 
loaded fuel cartridge there, but in order to insert the thermocouple, the cell 
could not be sealed completely.  Then a formal 
calibration would also be done after the experiment as well as before, and note 
any change.

With this particular run (5.2), the cell had to be sealed to protect the 
fuel/charge and was done under Hydrogen Gas, so the 
previous calibration (with the center thermocouple data) had to be used as an 
estimation of the core temperature.  A formal 
calibration was done without charge (dummy loads on each side) to a fairly high 
temperature.  Then the dummy charge on the active 
side was removed and replaced with the fuel/charge for the actual run.

The hope was to be able to remove the active fuel capsule after the run, 
replace it with a dummy loaded (Alumina Powder) 
cartridge/capsule, and perform a post calibration, but the active cartridge 
refused to exit once again, even with some elaborate 
tools Alan made to do it.  We know that the calorimetry changes (it’s a moving 
target), but we had no dummy post calibration to 
check it against.  Of course, a post calibration was done as best as possible 
with the active cartridge in there, with attempts made 
to kill any possible lingering reaction with Argon Gas...

Alan can elaborate on this more if there are any further questions.

I get the impression the Glowstick 5-2 test did not use full-blown calorimetry, 
and instead just used two thermocouples, one for the 
live tube and one for the blank.
