343i: CSR & Rank Lock solution

Games Other Halo

343i,

A flaw in truSkill and the Halo 3 ranking system, IMO, is that they are based on all your games played in a list/mode. This can and does lead more often than not players being locked at a rank at which they can no longer progress, for example, CSR41. The system does not allow for the CSR to increase after a number og games if a player has in actual fact, improved their skill level on the account of the vast number of games that have been averaged out.

However, if a CSR is based on the last 10, 20, 50 or 100 games, for example, the potential for ones rank to always go up or down is real. This allows for people to progress if at some stage they genuinely provide their skill which would be reflected over their most recent batch of games in a particular list/mode.

So, say someone has played a couple hundred games of SWAT and they are stuck at CSR29, they can not improve due to being rank locked at CSR29 based on all their SWAT game history. However, let us say they learned to strafe, juke, jump or whatever else(I don’t know) but the result was they had improved their skill…it would take hundreds and hundreds of games before their averages would change to allow for rank progression to occur, if at all. But, if the CSR system looked at you last 10, 20, 50 or 100 games, only (smaller sample size) people could then progress in rank based on a real improvement in skill.

The above would also have an additional benefit. It would not allow people to be locked into a CSR50. To keep it,they would have to keep playing at that level. But, if over say the last 10, 20, 50 or 100 games, they slack off, they would actually go down in rank!

Additionally, for those who purchase a rank or boost or whatever, the ill gotten CSR50 would after a short time start to slide downwards as the current holder of that CSR50s skill would be shown to be fraudulent.

The above system can be done.It has many benefits and allows for ranks to go up or down on a permanent basis, unlike TruSkill and, I believe, the CSR system.

Cheers

Csr on halo 4 is one of the worst thimgs ever… Want to know why?

Well, I play halo 4 swat and always get double kills to deaths and win most of the time… Great right? no… Because I won like 20 games in a row and did not go negative once but still my csr went from 39-37

SWAT is a playlist that is ranked individually, and win/loss and K/D ratio do not influence your CSR in this playlist. Individually ranked playlists simply rank you against everyone else in the match based on personal score. For our more competitive playlists, win/loss is the only criteria that you are ranked on.

This is not feasible. The amount of calculations that would need to be done is quite high as the system would have to essentially recalculate the last 100 (or whatever number) of games for each game you complete, re-do the skill update equation to account for all player’s updated sigma and mu (as the game is matched based on both values), based on the new data and old result, changing the rank of those people you played a long time ago 100 games after the fact.

Increasing the amount sigma increases before a skill calculation would also prevent rank lock.

I’ve won about 7 games in dubs and lost Two and im csr 1. Getting frustrated.

I have won 3 games in a row and have done pretty well and my rank has yet to update. It has no problem de-leveling me but when it comes to ranking me up it doesn’t.

CSR is not an average over all your games.

It’s a number that changes in every single game. Earlier games make it change more, partly because we have no history to trust, but even after establishing your CSR, it definitely changes every game. If the change isn’t large enough to move you a whole step, you won’t see it though.

Any player that wins / loses more / less than 50/50 (or consistently places above / below the middle in individual-style playlists) will see their CSR change. If you want your CSR to go up, you have to win more than lose, or place above the middle.

Thank you for that clarification. It is most appreciated!

Dear 343,

What the hell make you think that infinity slayer is a playlist
For individual scoring? Dont you think, that a good kd ratio is needed for a win?

I always have many assists and i die rarely. So my kd is 1.5. i won 70% in infinity slayer.
I am at csr 12 and my mate who rushes in with a bad kd got 30. in halotracker my skill is 47.
Really? Thats your vision how TEAM slayer should be ranked?

i would appreciate it if you could clarify this for me " win/loss and k/d ratio does not influence your CSR in this playlist" i’m not trolling or trying to be clever i just don’t understand what in fact does change your CSR.

Assists don’t cut it it seems.
But thats how Halo 4 is based on isn’t it, look at the DLC achievemtn 5 melees in a game. Basically run in and punch people…

Had 2 great and 1 good game of snipers yesterday and only a CSR of 10…
Considering I averaged a K/d of4.6 and we won all 3 games, seems a very low CSR…
