Well ... Of the fonts you list, I have only Arial Unicode MS
and Lucida Grande, but I get significantly different results
from you for the latter.  Would I be correct in thinking that
you are conducting your experiments using an Apple Macintosh ?
I ask because there is a common belief that Lucida Grande does
not render correctly on platforms other than the Apple Macintosh,
and it may perhaps be that the other fonts are biased in the
reverse direction ...

See attached results from Windows/XP.
