Good thoughts and great experiment!
I am very glad we have the desiccant pods and one with the space for a very readable gauge! I’ve only had my system since November and have only had to replace/recharge the desiccant once. The gauge, with fresh desiccant reads 10% (which is probably its lowest readout) and when it started creeping up (to approximately 14%) and the fact that I don’t trust the absolute accuracy of cheap hygrometers, I opened up one of the pods and found that the indicators in the desiccant had started to change color. I replaced the desiccant with new and dried the old. So far I haven’t had any issues with moisture and it’s largely because of the great ‘surround’ of dryers in my AMS enclosure.
Good job!
