I skimmed through it, it's a slightly different version of the same novel you write everytime :)
Not that I totally disagree with your basic premise, it's how you apply it in your made up scenarios with faulty assertions not based on reality and never try to make your assumption to match reality no matter how many times your called out. eg. You act like an engine that makes good 5000-6500 rpm power can't also make strong 3000-5000 rpm power which is obviously false.
Which 318 engine will generally make more hp @ 4500 rpms A or B ?
A, one that makes peak hp @ 4500 rpm or
B, one that makes peak torque @ 4500 rpm ?
