Not understanding contributor level right apparantly

Because he gave away some games which were unbundled (Borderlands, Day of Defeat, Portal).
On the other hand, everything which you gave away was bundled. Bundled games give you less value.
Therefore, you get less value :)

Bundled games don't count for full value. You can use this calculator to see.

Ah, So I was understanding bundled games wrong. I thought they where talking about, complete pack of Skyrim or whatever..

The value you see on your profile page is purely cosmetic.

If you give away something that was in a bundle before you only get vredit for 15% of the value when it comes to your level.

Searchable list of bundle games

Think of it as you have value of the goods and something called real value. The real value is what you get as CV. If your game is bundled you get 15% of the actual value. That 15% will be your real value.

Its clear to me now, thank you all for the quick response :)
