You're correct.

Please note this:  I've bought some "old" race gas that was lousy that
had sat around for several months after a racing season and the Audi
Club folks bought it at that track with poor results.

Would you explain this further?  I understand this is the case to get
benefit of being able to advance timing due to better gas.  But it seems
me, that detonation would be retarded as soon as a higher octane fuel
available to burn.  Am I mistaken?
