So i'm currently silver one, and I find myself being able to consistently get up to 90 lp till my LP gains start to get reduced significantly. Where at this point it is almost impossible to go positive because of the win to loss lp ratio.

This has now happened three times where i have gotten to 90 lp, Gained 5 or 4, then 1, 1 , 1 ,1 to 99 lp . This forces me to win atleast 6 matches in a row to be able to get to my promotion series. However whenever I lose, I lose up to 20 LP. This is really annoying because recently I have lost due to 4v5s.

Is there any way to fix this or just get lucky and hope no one disconnects?
