Forum:Pull ratios

I was working on a spreadsheet for my person use, showing all the packs and all the cards in them and percentages showing the likelihood of pulling a specific card, and it was going well, using this site, until I came to the percentages.

I came across some of the pages like Rare, Super Rare, etc.. and some of them had useful information that included pull ratios. Some other varieties of rares did not, for example I never saw a ratio showing for Ultimate Rare cards. Some of these ratios didn't match up with my personal experiences of drawing (I buy boxes). Because of this I decided to find out where these ratios are coming from and since I didn't see any references I searched the web after pages and pages of searching for rarity and ratios all I found where 3 sites.

A Lot of redirecting me back to this site.

1. A wikipedia page on the Yu-Gi-Oh! card game, the rarity section also cited no references. (Note: the pages for rare cards on this site are almost verbatim what is on wikipedia, which seems a little strange/sketchy...)

2. This site, http://farmhobbies.weebly.com/yugioh---classifying-a-cards-rarity.html, which has quite a few similarities to both the wikipedia page and the wikia pages here. (I'm guessing this is the source site for the information).

3. Another site, I can't recall what it was called, and I didn't bookmark it for a sole reason, that being while although much of the data matched the data from other sites it also said that the probability of pulling Ghost Rare cards was 1:36 boxes... which I know to be absolutely false considering I pulled 3 in one box.

So none of this ratio data seems to be supported by any "real" evidence that I can find or see.

To solve this problem I thought of a solution that I remembered from another wikia I saw a few years ago. Take a look at this page. http://runescape.wikia.com/wiki/Basilisk#Charms

It's a drop ratio for a game my brother used to play. It's on a 90% confidence interval which is pretty good. If we can start a log like this for boosters (a pull log), then we could formulate our own percentages and ratios through original research that would likely be more accurate than the current ratios given which seem to have little evidence to support them.

In the end the final result would look something like this:

Pull percentages Rare: No charms Super Rare: 66–67% Ultra Rare: 7–8% Ultimate Rare: 19–20% Ghost Rare: 5%

Represents 90% confidence range, based on a sample of 44,267 booster packs opened. 1 rare is pulled at a time.

It sounded like a pretty good idea to me, so I thought I'd share it for submission. I don't know who would be able to do it, if any one has taken stats or something like that it could definitely help. (I've taken a course in it, I just don't recall a whole lot.)

I really don't know how to make a template though, and I don't understand html a whole lot.Dragula42 (talk • contribs) 00:04, July 21, 2011 (UTC)Dragula42
