I've never had a problem with clones being identical in size to
the originals.  OTOH, the originals are usually boot drives and
I'm pretty careful to keep a bit of free space on them, one
side effect of which is that there's always some spare room on
the clone for the cloning process.

15% seems overkill.  I do try to make sure that there's always at
least 5% free space on my drive, though.  The last thing I want is 
a full disk.  Okay, maybe next-to-last (after a crashed disk)...
