I disagree, both sets of data look like a classic second order
quadratic response to me - and caffeine does not not suddenly become
100% soluble at 176 deg F, neither (in the real world) does a "wash"
with water at boiling point take place at 212 F. But, as Professor
Ingolfsson remarked (about polar bear ancestry): "This is just how I
interpret it. This is science - when you have little data, you have
lots of freedom."

However I am mildly surprised that the long term supporters and
advocates of this unnatural practice have never actually undertaken
(or caused to be undertaken) the key measurements at 0, 15, 30, 45 and
60 seconds.
