Andrew,

So...what am I missing?


The inertia of the pilot population, myths, misinformation, engine
manufacturer's law departments - all factors. "Show me the numbers" is
the old trick to silence the LOP opponents. They can't.

I take it you are familiar with John Deakin's columns on the topic and
engine management in general at avweb.com?
