From the above we might tentatively guess that paraxanthine is 1.5-2x as potent a stimulant as caffeine, while noting that measurements seem to be all over the place. This is in contrast to my subjective experience so far, where an equal dose of paraxanthine feels similar or weaker than caffeine.
Isn’t the point that a dose of caffeine is actually metabolized as a dose of caffeine PLUS paraxanthine metabolites? So you never actually experience caffeine by itself, and can’t really compare the two directly, although you can definitely model it modulo the rate of metabolism.
Same! This was becoming an increasingly common theme, to the point where I was having long in-dream discussions with friends attempting to evaluate reliably if I was dreaming—nearly always concluding that I was not dreaming. This started to disturb me a bit and I decided to stop this inquiry, which worked.
