Based on the fact that Glicko-2 is a tried and true formula based on hard math and statistics. As soon as you start messing with it and ignoring its output, you aren't getting correct data anymore.
the "better value" in an objective sense is the one that measures precisely the skill of players relative to each other. it is fair to argue that this is the "better value" since x-rank is a mode that explicitly has a player ranking leaderboard; it will tell you the positioning that you are on your region's leaderboard, and it awards badges based on your position relative to those other players. i would argue that there is an objective answer for what x-power should represent, judging by the leaderboard presentation that both games use
glicko-2 is a formula that can accomplish this precise measurement, given a series of wins and losses against other opponents in that same system. splatoon 2 (to my understanding) uses glicko-2 and does not modify it, calculating your power per game without any inflated points. splatoon 3 does modify it, meaning the data that glicko-2 would generate becomes wildly inaccurate, and it is no longer an accurate measurement of how people rank compared to each other
i think it wouldn't be nearly as one-sided a debate if it weren't for the fact that splatoon does seem to pride itself on these leaderboards. the fact that the game updates you constantly on what your positioning is on the leaderboard is in your region is a clear indicator that that's what they want x-power to represent, but they're using a formula that is worse at calculating that than what they were using before
edit, wow this messages gets really redundant whoops i didn't really proofread this lol
tldr splatoon likes to tell you how you're doing relative to other people even though s3's system is worse at actually knowing that data
here how it works:
int MatchesWon = 0
int MatchesLost = 0
Int AccumulatePower = 0
While(MatchesWon<3 or MatchesLost<3){
_______ // Splatoon 2 power of Glicko2 when a match finishes
_______Accumulate Power += Played match result
_______If match == win
____________MatchesWon +=1
_______else
____________MatchesLost += 1
}
if MatchesWin == 3
_______if Accumulate Power<10
____________FinalPower += 10
_______else
____________FinalPower += Accumulate Power
if matchesLost ==3
_______if Accumulate Power>10
____________FinalPower += -10
_______else
____________FinalPower += Accumulate Power
glicko was a method made for 1v1 games
a type of game that makes sense only the taking as an input who won and lost, and if the games is a draw.
glick-2 came as an adaptation in which now you can apply into 4v4 scenarios by calculating the amount of points simplifying a 4v4 into 4 1v1 for each player.
then noticing how limited glicko2 is limited and doesn’t evaluate in game performance. Nintendo decided to change in their game to behave like this.
and their intentions do align with the fact in S2 your performance doesn’t change your MMR outcome
Anarchy series is a method in which they implemented extra points based on the stamps you get at the end. If in S4 they decide to only use it as a rank method is a topic for another discussion.
when using statistics to determine data through Machine Learning there is a lot of different mathematical equations to recognize patterns and they are not strict. Even bots generated with AI using statistical models are not going to be always equal when you run your samples, and modifications will be made.
we saw the video that making matchmaking is not easy. even they mentioned about latency restricting players from ever play against each other. Thus the he region Tent and Tak were created.
my point is, some of you being strict with Glicko2 and taking that it should never be modified, given it started as a modification of Glicko. please I am waiting on proof or even a hint that Nintendo’s modification(see above for algorithm) is broken with any scientific data. From the current data, this modified Glicko2 is an improvemen compensating for features its original version can not calculate
Now if you all are just getting overwhelmed by the amount of 3k people, thinking it is a broken system or are just nostalgic about S2 I do not know
