Well, I suppose that I could do something like that.  I did write an
article for the local Amiga Users Group (NAG), and it's in the NAGRAG.
It was also distributed at AmiExpo.  Though things have changed, most
of the timings are still fairly accurate.

Now, let's keep our heads screwed on straight here... timings can be
 - well - uh - biased.  Compilers also rake havok on trying to get
 accurate results.  Another thing, is that if you set a program up to
 use IEEE and show off the 68881, then without it the program will
 run like a dead horse (or my ex-wife...)..

 I suppose that I can upload a semi-reprint of the article and let you
 see what I came up with (also remember that the 1000 will generally
 show a difference in speed on things with interlace screens, like
 (gasp!) Microbotics' FFUZ program.
