I'll gladly wear the *** clown badge if it shows I understand simple physics and math
What I’m saying is not the words your putting in my mouth but actual experience in what others say is going to happen doesn’t always happen or even remotely close to there slide ruler calculations.

Nothing more, nothing less.

Your specifics above on your question is not in question.
