Overdriven pulley how much is too much?

I do stand by my observations.

I do post what I have seen personally in
60 plus years in this hobby.

I do speculate on the causes of what I have
observed in person.

I do not post what I have read anywhere as I consider
that to be "here say".

I do not insult or impugn anyone who has different
opinions or experiences that differs from mine.
