Trying to get on the road to improving LMM economy, and timing is essential in the methods I use. But it seems to be a bit of a mystery.

Is this still a mystery? Not sure how anyone can effectively tune a vehicle without knowing which timing table is used.

...As far as altitude, I believe that low altitude is seal level up to 3500-4000 feet or so. Medium is from there to 7000-8000 feet (a guess, the words used were "like Mt Everest" which is much higher than 7000-8000 feet!).
Where does this reasoning come from, or observations?
