Heh. That's a fun chart. If that's programming aptitude, I scored 80 on that part of the broad spectrum aptitude test I got a sneak-peek chance to do several parts of. Well now I know why I'm so easily in agreement with "senior coders", if it is programming aptitude quotient. If it's just iq, ... pulls hood up to block the glare.
Daunting that there may be a middling bias getting apparent advantages. Evolution may not serve us well like that.
All the best garbage to learn from, to debug, debug, debug, sharpening those skills.
