I have taken a few of those online IQ tests and they show to be well above average. I don't believe those tests to be accurate and more importantly I don't believe IQ is an accurate measurement of anything meaningful. That being said I am an odd mix of morning person, night person. I function very well if I am out of bed by 6-6:30am, then I drop off about 11:00am. From 7pm-1am I again function at a high level. I typically only sleep about 4-5 hours per night and feel very groggy if I sleep more than that. I agree with most of the other responses. I think your peak production period depends on the season, type of work and lifestyle.
