I believe that, easily.

50 minutes later is not a very good statement. 50 minutes later than what? Luke went to a school that had the HS students starting later (9:00). Are they saying they will perform better starting at 9:50? If they are starting at 9:50 will they perform better starting at 10:40? While I generally agree with the idea, it would be good if they clarified a bit…

And I suspect this holds true for college students as well, and can be tested easily. Take a look at the grades and work from the 8AM students vs the 2PM students…

Walker's book, "Why We Sleep," goes into a lot of detail on this. Your circadian rhythms change as you age, and that should be respected.

50 minutes later than the control group.

I never had a semester without an 8AM class every morning. OTOH, you rarely had to fight for those classes at registration.
