I'm looking through the sources and can't find a paper on tolerance buildup times nor rebound effects after abstinence. Alas, I only have access to abstracts right now :( As for polyphasic sleep and napping, it is known that energy levels fluctuate cyclically throughout the day with two peaks, but I'm surprised that you plotted it with a sinusoidal curve that would suggest constant periods and surprisingly, constant amplitudes... of course, without axes the graphs don't say much of anything, but it's still a surprising presentation. You could justify it as being for a general audience, but it has significant risk of creating misconceptions, and weakens this article quite a bit. By the way, one of the papers finds "Caffeine consumption for 4 weeks also significantly reduced hippocampal neurogenesis compared to controls." Which is not happy news for me.
