I didn't just say 'I believe something else is true.' I used your data. Like I said, it is useful. But Newcomb clearly has the best numbers of the guys you listed with him. You treated him as though he is equal to everyone with as many or more walks than him. That list is a list of guys who are as bad as, or worse, than Newcomb in every category. It is poor analysis of the data available.
It would be just as useful to look at all the guys at that age, with 5.1 or fewer BB/9. This is my point. It is an arbitrary lower bound designed to compare him with guys even worse than him. A pitcher with 12 K and 1 BB per 9 has as much relevance in comparison with him as a guy with 6 K and 6 BB.
I'm not just saying 'Eh, I don't think you're right.' I'm saying that you can't use that data to say what you're saying. And I have given the reasons why.
I don't have access to that data to run these queries, so all I can do is use yours. I think it's interesting data, you just can't use it to say anything definitive.
