Exactly. Just about everything you read on this subject is folklore and
speculation. There is little data or scientific method.

It might be speculation but it's working for us. When
there is a lack of hard experiential data, you go by your own
experience, being careful not to make large changes. Many folks are
scared to operate engines in climates vastly different from what
they're accustomed to, and that's probably wise. It's not safe to
assume that the thing will behave as usual.
