Are you suggesting that OCW means "max charge/max pressure/don't dare to try it any higher"..?
Just trying to cypher your perception, not arguing......
OCW addresses barrel harmonics and the function they have on a measure of "accuracy".
Pressure and velocity are only a result of the entire system in motion, kinda like how gas milage and speed relate to a speed limit sign.
I bought into the whole OCW thing at one time pretty heavy. But I was alway complaining how finicky loads were. I stopped by Melvin Forbes place in WV on my way to Charleston, and that guy was a wealth of knowledge. He showed me how if a barrel is that finicky with 1gr difference, your compensating for other issues with the gun. Anyone that knows his guns NULA, knows he is big on bedding to take out those variations with harmonic nodes.
