The difference between real megabytes and metric megabytes (I don't
believe in mibibytes) is about 5%. 5% for the rounding plus 5% reserved
blocks probably makes up the missing 8%.
I know Chris mentioned using a reserved percent of 1 or 0. I am not
sure if it is well known that you can use fractions of a percent. The
reserved blocks also help prevent fragmentation by keeping large chunks
of space free. I would imagine in most cases you wouldn't need more
than a half gig or so of reserved space for that purpose.
