Put off by a long lesson that wasn't

I have been enjoying the Simple-ology Blogging course described in my previous post.
I'll even confess that my incentive for starting this blog was the offer of getting the course for free by posting the information about the course in my own blog.
I so enjoyed Mark Joyner's teaching methods that after completing his free Simple-ology 101 course, "The Simple Science of Getting What You Want," that I signed up and paid for course 102, "The Simple Science of Money."
In fact, I already plan to also shell out the necessary money (scientific or not) upon completion, to enroll in his third basic course 103, "The Simple Science of Personal Energy."
So in my post I promised to report on my experience with the blogging course.
It has been great.
I discovered a techno-glitch that is probably not noteworthy except for the effect it had on my participation.
When I logged onto the video file for Lesson 6, the time indicator at the bottom right showed a total time of 13:44. It was late, and I was tired, and decided that this was simply too long to tackle that night.
How could less than 15 minutes be too long?
A signature part of Mark Joyner's methodology is that you view each lesson in a narrated video, then take a multiple choice test on it, then read it in the course book (a free download in PDF format) then read it out loud, then listen to it (another free download) in MP3 format.
I instantly calculated this (I'm old - so I was taught to do simple arithmetic in my head) as needing a time commitment of nearly an hour.
Most lessons are in the 4 to 7 minute range, so even multiplied by four, are easy to complete.
Well, today being Saturday, and hating to lose momentum, I decided to just do the lesson.
When I read the lesson, first silently and then out loud, it didn't feel like it was taking me close to quarter of an hour.
Imaging my surprise when I played the MP3 and the elapsed time was 5:19!
Baffled, I re-opened the video and paid attention to the parade of seconds in the timer - they were counting off at least 2 1/2 per actual second.
Some mis-calibration of the video timer - with no impact on the actual performance - was the reason the video "thought it was" over 13 minutes long.
So now I am ready to do the next lesson tomorrow, no matter how long it "claims" to be.
I've learned a lot more about blogging, and one more thing about myself:
I sure can get hung up of trivial details!
If you read this, please let me know if you think this demonstrates a fatal flaw or just an "interesting" (I hope) idiosyncrasy.
Thank you.
