yes they had a hypothesis. that’s how science works.
You left out the other benefits the study found. those benefits seem to be quite significant. In fact, I will go as far as to say that sleep has been well associated with student performance.
You remark comes off as disingenuous and not ready for serious review.
At some point doesn’t this come down to the ISA? A CPU running at 3GHz gets 3 clock cycles per nanosecond.
I bet there is a fair amount of optimization in the compiler that leads to back to back assembly calls of reading the clock register. If subsequent time.Now() calls happen within 3 clock cycles of each other, can you really fairly expect unique nanosecond precision…
