I goofed.

But I did find out what having a math co-processor can do for you.
When I repeated my orbit-prediction benchmark on a another 6300+,
the results were much different (192 seconds vs. 22 reported previously).
Sure enough, I've found that the original machine had an 80287
installed. Of course, it is not fair to compare the ST's performance
to a machine with a co-processor. However, I think the ST should in
theory be able to beat 192 seconds. Several people have already
volunteered to try the program on various machines/compilers
(including the Amiga with 68020), and I will post the results.

The updated chart is:

machine		compiler	run time (s)	accuracy
===========	============	========	==========
520ST		Lattice 3.03.01	480		very good
6300+       	Microsoft 	192		excellent
6300+/80287	Microsoft 	22		excellent
VAX 11/785	Unix V cc	4		excellent
Amiga 1000	Manx  -lm	25		poor
