I start playing again this season after returning from a long break(since s4). Im curious how MMR effects the LP Gained/lost in ranked games. I have been a Kat main now as of recently win rate at about 54%. I was gaining 17LP for a win and losing 18LP for a loss. Got promoted and now I am gaining 16LP for a win and losing 18LP for a loss. Can anyone give a good explanation of this?
You're playing against your own global winrate.
Falling to about 40% global winrate means at some point you've started playing with lower players and still lost a fair amount of games. Your MMR is still lower than your current rank despite your recent wins. Worst, it was so low and your winrate improvement so sudden you're actually widening the gap between your MMR and your rank, that's why you're getting a stronger LP penalty for now.
Inconsistency incredibly hurts MMR but isn't affecting rank as fast, so keep going until the game can finally sync your rank and your MMR.
Riot doesn't share their system.
My best guess. As MMR is the core, MMR uses Ranges, The goal is to have MMR = The mean average of their good and bad standard performances. This is not inherently accurate, it has an adjustment period, and incase you ever improve, the ability to return to climbing at any point. Or sink if the opposite comes true.(not always player fault, buffs nerfs, reworks are things that can be negatives for a player.) Now id make my Tiers and Divisions represent the entire ladder, and break it down by ranges, that way my Tiers actually have some meaning, they do represent skill well once MMR is accurate.
Then for LP gains I would make it off an accounts current MMR compared to their Range. Id use the range because its easy to generate as a value. Then would compare the players New rating after a game to that. If its to under that Reduced LP gains. If its above, accelerated gains. Balanced for being inside it or near the center of it.
How id approach it. No idea how viable or realistic that would be. Im still learning about the math still behind Elo systems.
Some of it is just RNG based off what the system calculates as your chances of winning a game. But all you rly need to know about MMR is that if you are climbing, and keeping it higher than your rank, you'll gain more. If you're losing alot, you'll gain less. It's trying to get a feel for where your skill level is actually at but matching you against higher and lower ranked players, and if you're consistently winning against players higher ranked, you'll get more LP to put u in that rank, and vice versa.
Basics of MMR is
If your MMR is lower than the average of your current division, you will be rewarded less LP for a win but lose more LP when you lose a game.
If your MMR is higher than the average of your current division, you will be rewarded a lot more LP per win and lose a lot less when you lose a game.
