...the question is simple... WHY go through this time consuming exercise
</p>

Honest opinion? - You don't have to. Save your time and stop doing what isn't really needed.
Personally I'd say that 99.99% of the defragmenting being done around the world is unnecessary.
Hard Drive capacity and technology has moved on, processor technology has moved on. - But most peoples thinking hasn't caught up yet.
Many articles written about defragmenting haven't caught up yet.
Or don't want to because <em>"It's not needed most of the time"</em> doesn't make for a long article. (Or sell defragmenting apps).
Unless your disc is in a real mess then you won't notice any performance difference between before and after running a defragmenter app.
Consolidation/defragmentation of a spinning magnetic disc could be important 10, 20, 30+ years ago - drives were smaller and slower, RAM was smaller, computer processors were slower.
It's not so important nowadays.
Todays larger drives have plenty of space so don't often need consolidating. (only if they have been used a lot with a lot of deletes and re-writes over time).
For the average user it isn't a problem.
Files being fragmented means they will load into memory (RAM) a tiny bit more slowly, we are talking about milliseconds difference with todays faster processors which means you will hardly notice the difference if you notice at all,
However, some people still like to see a 'tidy' drive when they run a defragmenter.
But that's a self fullfilling prophecy - <em> If they didn't run a defragmenter then they wouldn't know it was 'untidy' anyway</em>*, and wouldn't notice any difference.
So they are looking for a problem that isn't realy a problem.
*You may have noticed that the built in Windows one doesn't show you a drive map anymore. That's so you can't see if the disc is 'untidy' or not, because it doesn't matter.
But if people stopped making/selling defragmenters, and especially if Windows didn't include one, then there would be moans and complaints.
As long as people expect to see one in Windows then it will still be there.

All defragmenters will report different things.
In this case Windows will be ignoring files below a certain size, or with less than a certain number of fragments.
Again, because it doesn't really matter.
(I'm guessing that over time the Windows defragmenter/optimiser will show less and less until it becomes simply another background maintenance task that doesn't have a user interface, removing the drive map and not showing all fragmented files look like just the first stages of that process).
