There's a wrinkle though.
Once you have earned your allotment of cards for a game, you're eligible to get booster packs, one is spawned globally each time someone crafts a badge.
Each booster pack has 3 random cards for that game. It's always three, regardless of if a game takes 5 or 15.
So you have to run through iterations for each set size to get the number of L1s*, but ultimately, the number of people that can have badges is less than the number of people who own the game.
*(It's 75% for 6 card sets, a bit higher for 5 card, but drops from there.)
What you do with the cards pmuch falls under which camp you want to be in.
