How is your level determined?

https://www.steamgifts.com/about/faq

-You get the current retail value of a game if it is not bundled. If the retail price drops in the future, your value for that game drops as well.
-You get 15% of the current retail value for games that have been bundled.
-If you give away more than 5 copies of a game, you get less and less value for each extra copy you give away (explained in the FAQ).
