I tried this two years ago with a friend. We weren't able to do it for very long, and we had a lot of trouble staying to the schedule (and not oversleeping).
Eventually, you reach this sort of zombie lucidity where you're awake and conscious, but you're not 100% there, in my opinion. I'm not sure if that affected my critical thinking skills, but certainly some part of me was always asleep on that schedule.
Hey, maybe this would have gone away if we'd been able to stick to it for longer. It was absolutely one of the funnest experiments I have tried and I want to do it again sometime.
I got through about 2 weeks and while the first 4 days were hell, after that it was like a constant 90% alert. It was a little weird ever hitting 100%, but extremely weird not to space out and dip lower. I kept waiting to space out but it ever happened.
