When studying the various fuel the specialty formulators are selling
it is obvious that volatility is important which must be the reason
they offer so many formulations.

The first link to chevron was dead so it sent me to their search page. The
second page was a bit better and it said exactly what I've been saying on
this thread. Any fuel that has more resistance to detonation than octane
will have an octane rating higher than 100.
When I was in technical school I had the same argument over volatility and
octane rating. It was the opinion of my class mates that because high
octane fuels were more volatile than they were actually more explosive,
(would flash at a lower temp). I ended up doing a paper on the transitions
of the fuel in the various stages of compression to demonstrate why high
octane fuels were used in high compression engines and the flash points of
some readily available fuels
I guess to try to cut to the quick of it is that it looks to me that you are
trying to compare apples to oranges. They are both fruits, they are both
more or less spherical, they both grow on trees but they are very different.
