Personality System Data Collection [WiP]

I do seem to hit a Charm exp cap, here is a screenshot: link


Any idea when and how to obtain these medals?

Edit: Also: Lvl 20 with 479 exp equals 5042 total exp. It could be there's a 5000 exp per day cap and that I overflowed it with the +90 Charm equips.

The cap for Charm EXP is 5000. Every other stat is 500.
You can tell by scrolling over to the trait in your little chart.
