Similr to user.cardsCreatedCount this increments/decrements when cards are added or removed. Unlike the normal user.cardsCreatedCount the raw version keeps counting even if you’re a free user editing cards in a paid user space (where cards wouldn’t normally be counted). This is so the cards created count in user details is accurate.
This is to fix the issue where you’d have a space with lots of contributors and you’d erroneously see 0 cards created when clicking on the free users. It’s purely just a vanity metric for fun and doesn’t affect any free user limits
