Look, I'm sorry you missed the lesson on connecting the dots in kindergarten, but you really should have sought remediation there. Follow this (if you can).....
Look at what the BP stat is used for in its definition. It is a production rate used in a system to determine comparable players. Since you seem to have some difficulty with vocabulary too, I'll put that in layman's terms, oops that was too big a word for you, I'll break it down Barney style. What that means is that it is a percentage (rate) used to do exactly what you were doing upthread, comparing players. So, in other words, BP, a site at the forefront of modern baseball statistical analysis, uses K/PA rather than K/AB when doing exactly what you were doing earlier, which is what I said to begin with. The fact that you missed this and had to have it explained to you is totally unsurprising and hilarious at the same time.
