Yes and No, sometimes game devs add a DLC with achivement, then once 100% in a Original game is not anymore, but who kno what has happedn at your value's.

Games with "profile features limited" or "steam is learning about this game" on their store page are meant to not be counted in showcases, but from what I've seen they occasionally bug out and get counted anyways.

My perfect game count has said 22 on the completionist showcase for awhile, even though it is actually 24, but today i looked at my profile and noticed, it actually said 24! The two that I noticed were excluded from the list before were even able to be showcased. But, i just looked at it now, not 3 hours later and its back to 22. Very weird.

Showcase data is compiled and stored as static values upon certain events. It's not calculated in real time when your profile is loaded. That would cause too much load on servers.

Occasionally that data isn't calculated correctly for whatever reason and may not be entirely accurate. Usually it will clear up on its own eventually. Sometimes you can force the recalculation to take place on your own by earning a new achievement.im any game.

I've heard about that, they are limited, which is why it surprised me. I think that is probably it though. One is a small game (Like 10 reviews), but the other is like 2k reviews and a couple years old, so that is a bit stranger that it is profile limited.
