LP gain and MMR

FA Dragon·Jul 13, 2019·1 votes·1,630 views

So I have been playing Ranked for over a year now and a friend of mine is in the same elo range as I am. Currently I'm in Gold 3 and he is in Gold 4, but I gain less LP per win than him even tho my win rate is higher than his. I currently gain 18/19 LP per win and somehow he gains 27 LP per win so I was wondering if anyone knew why that is. Even when I go on huge winning streaks like 10 or 12 games in a row won with good kda, cs, KP% and vision score my LP gain doesnt increase, it remains at 18/19 LP per win. And even if he goes on a big losing streak his gain remains at 27 LP per win. It's really frustrating and I dont know why the system does this, our MMR should be identical but somehow I'm being screwed out of LP. Even in season 8 before the ranked changes I checked my MMR on op.gg and even when my MMR was 2 devisions(so for example I was G3 at the moment, my MMR would be G1) above my current rank my LP gain wouldn't even increase.

Does anyone know why this is? Please help

MMR difference most likely https://na.whatismymmr.com/FA%20Dragon (I've found this site to give me reasonable results when trying to understand my gain/loss ratio over Silver-LowDiamond but I'll remind that this isn't Riot's explicit MMR system) You can look up your friend's mmr too. Winstreaks don't matter, it's just the MMR that causes the Win/Loss ratio to be favorable or less favorable. If you want to bolster your MMR, duo with higher elo people and retain high impact scores (Not only KDA) in other areas while doing so. If his Win/Loss ratio is higher than yours at the same LP score, then it's clear that, according to riot's system, his MMR is greater than yours. From this, complaining or attempting to reason this as a fluke is useless. Instead, just find faster ways to gain MMR rather than trying to reason with the system.

Thanks for your comment. I checked his MMR, his normal games is pretty high and his soloq is gold 2. It's still weird to me, cuz he hardly plays soloq

I am pretty good with MMR systems. Provide me your friends Op.GG and I will take a look.

Low # of games = Higher K factor = Bigger MMR changes per match.

Due to Weight on early matches. K is the variable used in Elo systems to represent system uncertainty.

Some one like your friend who has under 40 games is considered higher uncertainty them a player like yourself sitting at 210 matches.

Also related to MMR. Checking the average of games it looks like your friend is playing at or higher then his currently assigned Tier, where as you tend to play At or Below your assigned tier.

Far as I know there are ways two ways to build tiers. One is a leaderboard tied directly to Population, which is kind of terrible as inactivity will sink players. The other off MMR ranges, which only has accuracy for low uncertainty accounts.

Still doesnt explain how I dont even get 21LP back when my MMR was 3 tiers above my current rank. Also when I did my placements, I won every single one.. riot said you would gain a lot of LP(like 50+ per win) but somehow I only managed to get 55LP for my first game and then every other placement match after that was 27LP to 30LP

I'm working a 12 hour shift so I wont be able to do a detailed reply till late or tommrow. I need some details. Did you do placements befor or after riot removed positional ques? Same for your friend.

Did you guys play preseason and if so what ranks did yall end preseason at.

Do you know what a title (tier and division = title) is made to represent and the common ways to build then?

This is stuff I find interesting and the more data I get from players helps me figure out riots system so I am pretty curious what your responses will be and to see if they match my assumption.
