Contributor level too high?

Level 4 is 100 dollars.

Were the giveaways for multiple copies of a game? Sometimes I don't pay attention to that, otherwise if they were non-bundled giveaways then yeah level can go up quite quickly...

maybe the CV for lvl 4th is 100 and he giveawayd non bundled games, then he will get the entire CV amount, for example see mine
75 games sent($669.25) most of them bundled, and im exactly 4.00

he could have made 4 ga for that $800 software

If the games were never bundled you get full points for them, check the faq

I went straight to level 5 with 3 GAs of Mortal Kombat X Premium back when it cost 90$

It's a hack called unbundled games :P

Everything is clear now, thanks for your answers.
