Yes, this didnt seem like it was useful for daily use.

48 hours without sleep isnt realistic for most cases, and I dont think these results have anything to say about daily caffeine.

Also, I think the best advice is to learn your body. I cycle caffeine every few months. 2 cups all at once before I need 5 hours of productivity.

Yea, I think the 48 hr sleep deprivation is not applicable to most people. The task also is a kind of "vigilance" task. I don't know if it applies to any kind of productive thinking. They also studied chronic sleep deprivation, maybe that would be helpful for people.
