Mike Friedman mentioned some break-in strategies (not against the 
Club, but to gently break in a Miata engine).

I have a question about this one:

	2: Run the engine over it's entire RPM range, but don't
	hold any one setting for more than a minute or two.

Why does this matter?  For any given engine speed all the parts in 
the engine follow the same motion.  I have heard this for years 
from people who I thought were knowledgeable, but no one has ever
explained it.

Thanks,
	QF
