An excerpt from a book

I have read so many analysis of phonomenal, but this excerpt from a book is exactly what we would say, taking it literally:

In a number of suttas,2 it says the Buddha, on the night of his awakening, after
moving through the four jhānas, spent the first watch of the night remembering
his previous births as described in this power. Because India is near the equator,
a night there is about 12 hours long all year round. Since there are three watches
of the night, the length of each watch is about four hours. If we “do the math”
and compute how long the Buddha-to-be had to remember each of a hundred
thousand births, it comes to one-seventh of a second.d He had to remember eight
things about each birth in one-seventh of a second and repeat that in the next
one-seventh of a second and so on nonstop for four hours. The human mind can
only process at most about 40 conscious moments per second.3 If he had to know
eight pieces of information in one-seventh of a second, that’s 56 conscious
moments per second—and we haven’t even addressed the “many aeons,”
whatever that number might be. And you can’t say, “He’s the Buddha!” because
that won’t happen for another four to eight hours. So it seems we cannot take the
description of remembering past lives literally, at least for the Buddha on the
night of his awakening.

Yes, the analysis is really detail. I wonder if it is necessary though since whether it is one watch or two watches is not important but that the Buddha saw through his previous life.
