But does that tempo sound good for the song? The fundamental of the note that the key is in is not the only thing you are recording! There's so many overtones and harmonics that every instrument would produce, for every note in a part that are far louder than your "perfect" tempo syncing with a fundamental!
Surely the groove matters more?
There's also no need to swear at people who are disagreeing with you. And also, it's probably best to take into consideration how top engineers/producers do things, they're at the top for a reason.
