I agree with this for the most part, remember why an engine needed to break it, to wear some parts in and at one time get all the left over bits of metal from poor machining, manufacturing is so much better now that I have only seen one locked up motor under 5k miles presumably from not breaking it in, it was a brand new Pontiac gran prix, a 1996. That said, there are many other moving parts in the trans and diff as well, so IMO(I did not buy mine new) I would drive it 1k easy change all the fluids and red line away..JMO. On topic I agree with others there is no perfect rpm, you will learn your car and engine and shift by sound, it will become second nature, not all situations are identical, we have hills everywhere, nothing it flat, which sometimes it requires more engine power to achieve the desired acceleration. I know when my car is going to hit red line without looking at the tach, you simply learn the car. Drive it and see what feels good, thats all.
