No matter if the set point is set at 230 C or 450 F all this is is energy storage as when the OA hits the bottom of the bowl if your system is sensitive enough you will find that the temperature will immediately drop to below 150 C or  300 F due to the latent heat required to change the state of both the water of crystalization and for the sublimation of the OA.  It can also be seen that once the temperature of the vaporizer rises above 200 C or 400 F the sublimation is complete and one can move on to the next hive.  One might not see the temperature drop as mentioned sometimes due to the thin layer of oxidization on the bottom of the bowl and if the bowl is wiped around with a stailess brushh which disturbs the layer on the bottom you will again see the temperature drop.  This will also bring into disrepute as to what temperature the OA is subliming at as when the temperature remains high it indicates that there is a barrier between the bottom of the bowl and the OA.  One must also take into consideration the actual design of the bowl and thermocouple, the heavieror thicker the bottom of the bowl and the heavier the thermocouple the more time will be taken for the temperature to change.  So just a few thoughts to add to the confusion on OA vapor.
   About the paper being discussed it would be good to know how and when the OA vapor was applied,   The amitraz treatment  is normally applied over 42 days, I wonder if the OAV was also applied over 42 days.
