There are other considerations as well.  Just because the engine is capable
of placing dots every 1/400 inch doesn't mean too much.  The size of the
dots and their shape is important, too.

For example, if the dots are 1/200 inch in diameter, then the added
dot resolution might be significant for large characters, but not
for small ones.

Appearance - real-world resolution, if you will, is the real measure.
