That's awesome.... I am still doing my best to play without a type chart in front of me. I don't want to have to rely on all this extra data to help me succeed. It's crazy, there is SO much to learn and memorize... types, moves, stats, etc. The more you know, the better you are.
It's cool to hear you've been playing since yellow. I started with BW1, and didn't start actually thinking competitively until about mid BW2. I've been enjoying it since!
