[CQ-Contest] Caffeine vs. Placebo

[Robert Shohet]

Yes the chart is confusing but I think that the participants were split into
two groups (red and black) and then caffeine was administered AFTER 48
hours, resulting in the jump in performance AFTER 48 hours.  Of course, as
you would expect the performance was pretty much the same for the two groups
in the 48 hours BEFORE caffeine was administered.

All this proves is what we knew all along - that caffeine DOES increase
performance of the sleep deprived for some time after administration.  It
doesn't say the other part of what we know, that as you get more and more
sleep deprived, the effect of the same amount of caffeine is less and less
(something to pay attention to!)

Anyone who has been operating contests seriously for years already knew
this - HI!
