I seriously doubt any person with intact sleep regulation could go anywhere near eleven days without microsleep. Wikipedia is wrong in suggesting that was the case with Randy Garnder (Wikipedia is in general not a reliable source on sleep issues). There were at least strong signs of microsleeps before the fifth day (noted in the study[0]) and my guess is that occasional microsleeps would have happened earlier. They did not closely monitor for microsleep. [0] Gulevich et al.

The true record for sleep deprevation may be held by someone with fatal familial insomnia, although it sounds like stage 1 sleep is at least sometimes possible with that condition so it might depend how you count that. Morvan's Syndrome is another one that can cause an extended lack of sleep. https://en.wikipedia.org/wiki/Fatal_familial_insomnia https://en.wikipedia.org/wiki/Fatal_familial_insomnia https://en.wikipedia.org/wiki/Morvan's_syndrome https://en.wikipedia.org/wiki/Morvan's_syndrome
