"Limiting manifold pressure for continuous

This sounds like a Constant Speed prop chart to me. As you know MP
isn't relavant for fixed pitch props. The manual may be for an engine
that can have both CS and fixed mated to it.

Patterson's note of the chart referenced from altitude, as opposed to
manifold pressure, causes me to scratch my head, too.

May I ask why there is a limitation? I'm sure its not good to lug the
engine, and its impossible to lug an engine having a fixed-pitch prop.
But wouldn't the damage come from extra heat generated? So the temps
would change, but they could also be monitored. Yes, Lycoming knows
when their engine will overheat, but environment is not isolated from
it. Are rpm and manifold pressure so isolated to itself?
