Roger, I don't think this is about experimentation at all. It's just that
so often someone jumps in here with an absolute statement about something
that needs to be done or something bad will happen. I used the word "will"
because that's how it usually comes across. It seems that much of this
comes from someone who read it somewhere on the internet so it makes us a
bit skeptical and usually all we ask for is some data to back it up. Other
than Rotax says so, none has been provided here.
