My Data On Key Fragment Drop Rates

Fight with Honor on PBE!

######Whew, this post was hard to format. I did it though! Since Key Fragments are not going to be connected to wins anymore (see link!), I thought it would be a good time to publish my data since it will be much more difficult to track with the new system.

What I have been doing since February 6 is recording my Key Fragment drops. Whenever I get a win, I note whether I got a Key Fragment and how many people I was playing with, since the number of people influences the drop rate slightly. Here's what I've found. For the sake of post length I am only going to post one cycle in its entirety, just to prove that my data is legit. (Mods please don't delete this post for naming and shaming, these are matches are only normals so most people won't see the names in the matches anyways.) ##Cycle 1: Feb. 6 - Mar. 7

To summarize what happened, I got four Key Fragments in a row, one from five wins, one from four wins, another, another, one from four wins, one from four wins, and I got in two more wins but no Key Fragments before my cycle ended. That's 10 Key Fragments from 25 wins, which is pretty lucky, as you'll see from my later data.

In my second cycle, I got a Key Fragment, one from two wins, another, one from two wins, one from three wins, one from two wins, and I got in three more wins before my cycle ended. That's 6 Key Fragments from 14 wins.

In my third cycle, I got one from four wins, four more Key Fragments in a row, one from eight wins, two in a row, one from six wins, one from ten wins, one from five wins, and I had six wins with no Key Fragments. That's 11 Key Fragments from 45 wins.

In my fourth cycle, I got one from my first win, one from two wins, another, one from three wins, one from four wins, one from two wins, another, one from fifteen wins, one from four wins, one from seventeen wins, and I have five more wins with no Key Fragments. That's 10 Key Fragments from 55 wins.

In my fifth cycle, I got two Key Fragments in a row, one from three wins, one from four wins, one from three wins, one from four wins, one from ten wins, one from six wins, one from seven wins, then two more in a row (huge luck), then I got thirteen more wins before Honor 2.0 was released and the Key Fragment drop rates changed. That's 11 Key Fragments from 54 wins.

So I haven't gotten twelve Key Fragments per cycle yet, and I'm playing a decent amount, though not as much as the average League player I think. I haven't gotten nearly enough data to find out the "pity drop thresholds" for each Key Fragment, but I'll list out my maximum amount of wins for each Key Fragment anyways. Maybe I'm close.

Fragment #Max Wins
14
22
31
43
55
68
73
815
97
1017
115
1213

Since each Fragment has to have an equal or higher threshold than the last, we can assume that Fragments #2-4 have at least a four win threshold, and that Fragment 7 is at least eight. Fragment number 9 must be at least 15, and Fragments #11 and 12 must be at least 17.

What do you think about these data? Are you happy that Key Fragments are only linked to Honor now, not wins? Discuss!

According to that post I linked in the original post, you should be getting pretty much the same amount of Key Fragments as today. The Key Fragments are tied to Honor and not wins though, so you don't have to feel bad about not getting Key Fragments if you go on a losing streak. On the other hand, you can't flame or troll other people or your Honor level will be too low to get Key Fragments.

Hmm thats interesting. I wonder what happens if you dont really get honors, I know my friend doesnt ever talk in chat and normally just plays decent in the games we play in, nothing to deserve an honor exactly. I hope that doesnt effect his rate of keys

According to the original post I linked in my post,

{quoted} ◦◦◦ Everyone who's level 2 [starting level] or above gets all their free key fragments by just playing games without getting hit with penalties ◦◦◦ Earning Honor votes is not required to get your keys ◦◦◦ Winning is no longer required to earn keys.

If you flame or troll, how does your honor level go down?

The post says that only getting penalized will drop one's Honor level. I'm not sure about how legitimate reports that don't punish will affect players.

~~I don't believe that it's an "at least x" win threshold design, and it's actually 'at most x' since they have safeties in place to prevent excess bad luck (although you can't determine what that x is from your data, although you can determine that the upper limit is at least x where x is each of your wins there). You have a certain probability of getting a key fragment on a win, and that probability decreases with each fragment you get per cycle. So for example, getting the 12th and final key fragment for a month might have only a 1% chance of dropping on a win, but you could still get it the first win after getting your 11th. ~~(edit: On rereading, you understand this. The wording in your last paragraph threw me off a bit, but it's probably ok.)

Still, linking thing to honours and raw games played instead of requiring wins should be a positive, although the tuning is supposedly such that people will get basically the same number of fragments. Presumably they're assuming a 50% winrate on average, so those with somewhat higher than 50% winrates may actually find them slightly slower, while those with somewhat lower than 50% winrates may find them slightly faster...although we'll have to see when it actually releases.

Yeah I remember a Rioter saying that there was a threshold of wins where the next one would guarantee a Key Fragment so that RNG couldn't screw players over too hard, but for the life of me I can't find that reply, and I feel like I've looked everywhere. It might have been on reddit.

I think linking it to Honor will be a positive too, but it makes me sad because it means that my project won't have any more meaning in month or so. :( I wonder if just playing a matchmade game will start a Key Fragment cycle. If so, then I'll still be able to collect data, I'll just need to collect more since I'll have to include losses too.

There was a forum and/or reddit reply that confirmed it long before the ask riot thing confirmed it, but this ask riot thing confirms the bad luck protection thing and is much more accessible.
