Here is a fully 'non-commercial' website offering a New Testament Excel based reading schedule download.
5 minutes a day.
5 days a week.
Thereby completes the New Testament cover to cover in exactly 52 weeks. www.TheBible.bz
Not to suggest that you are disputing the arithmetic,
my understanding is that you are simply saying
that you * are surprised by the suggested time it typically takes to read at 5 minutes per day x 5 days per week x 52 weeks divided by 60 minutes per hour =
21.66 hours. Got it.
And as follows below (see ">"s) ....
my view is that the website is simply stating '5 minutes per day' so as to notoverstate the commitment one would be making by using the download-able reading schedule.
I have used the schedule myself and found that most of the days,
consistent, with your above,
is that it does not take a full 5 minutes every day ...
although, some days take me longer.
In support of your view, I have found that ...
> The typical length of recorded 'out-loud' reading CDs per Amazon is 20 hours.
> Internet searching on length of time to read New Testament offers a range of 18 - 20 hours. Conclusion:* You have been blessed with better than 'average' reading speed.
P.S. The value, for me, of reading s-l-o-w-l-y
is to try to be able to see the riches of The Book in detail/depth ....
for which my average brain needs to do at a s-l-o-w-e-r rate than that of speedier readers/comprehend-ers ...
the 'slow absorption rate' offered by www.TheBible.bz , for me, works well.
