Question about ranked LP gains/losses
So I'm currently in Plat V attempting to just get Plat III or II so I can place in Plat V next season. I recently realized that after getting into plat, my LP gains went from Win 21 Lose 16 to Win 20-21 Lose 19-20. Is this normal? I'm basically only profiting 1 LP per win and loss. I'm 14 ranked wins ahead of losses does this mean my current mmr/elo is horrible for Plat V or does it mean that Ive just been losing a few more games lately than winning? In my imgur that I linked, everyone was Plat III or higher, shouldn't this mean my mmr is somewhat decent?
