I was agreeing with you that real world metrics would be useful.
I was making a couple clarifications. You seemed to imply that real-world metrics can be a substitute for big O, but that's not the case, they do different comparisons.
Also, I was pointing out that the 10ms vs 9ms example isn't a set of numbers that would indicate one algorithm is better than the other, just that one implementation is better than the other.
