This one you are correct on and I thought of as soon as I hit send.
Please note: it is not to say that one can not do this, but I know of no
program that actually takes advantage of this.
Take care,

I didn't make the calculation, but if it was good, then the defragmentation
doesn't change anything.
The defragmentation would change things only if more than one cluster of a
file is occupied only partially.
In that case, the content from other clusters will be moved to fill all the
clusters of the file entirely, and leave eventually only one cluster
partially occupied.
