10 cups? That's a lot of coffee. I wonder if certain other factors might be
factored in, such as polyuria and caffeine-psychosis. Polyuria could deplete
the electrolytes couldn't it or does the brain have some privilege in this
regard? If one is amped out on that much coffee all the time, would their
diet suffer? Anxiety or stress levels could interfere with learning couldn't
they?

Of course the law of diminishing returns could rear its ugly head too
couldn't it as long term use might relate to the body setting its homeostatic
mechanisms to regain some sort of balance?

These might be naive questions, but I think they're relevant.
