What does a booster box get you?

As you saw in yesterday's post, I opened up 4 Madoka Magica booster boxes (80 booster packs) and tracked what cards I got. In today's post, I'll be talking about how many copies of each card I got in total. I'm focusing on each card number and getting a playset of 4 copies, so I'll be merging R/RRs with the SRs, RRRs, and SPs that are parallel copies of them.

Here they are, sorted by card number:

Summary of the data:

• I got at least 1 of every non-parallel card, and the parallels helped me hit 4 copies on several cards.
• There are only 2 cards with only 1 copy and both are RRs.
• I got at least 2 copies of each rare, and 4 copies of several.
• I got 3 copies of only two RRs, and my SP pushed one of those to 4.
• I got an average of 2.85 copies of each card.

Based on that, here are some estimations:

• Opening 4 boxes will get you at least 1 copy of each card.
• 6 boxes will get you a an average of 4 copies of each card, but you'll have some cards with less than 4.
• A case (16 boxes) will have at least 4 copies of every card.
• 4 boxes gives you no extras (over 4 copies) to trade.
• A case will give you almost 320 extras.

And from those estimates, I can give this advice:

• Buy 2 boxes if you want to build just one specific deck, since you can trade the cards you don't care about for the ones you need.
• Buy 4 boxes if you want at least 1 of each card, but you'll probably need to trade away non-extra cards to get some cards you want.
• Buy 6 boxes if you want 4 of each card, since you can trade your extras for the ones you opened need more of.
• Buy 16 boxes if you want 4 of everything without needing to trade.

Have you had different experiences, or do you have different strategies when buying boxes? Let me know below.
