Of course it's often bad. Everybody knows that already. That's why there's no
program on Earth that has a knight piece/square table where a8 is higher than
e5. What you are proposing is to decrease that value to account for major,
short-term tactical issues that may or may not exist. I don't think this is a
good idea, but you don't have to take my word for it. Download Crafty and try it
out.

I have no idea what you're talking about.

But analyzing the positions will not necessarily tell you if you gained or lost
an ELO point, that's the problem.
