Ive won 60% of my last 20 games.

And this is why you should not look to 3rd party sites that do not have the correct stats.

op.gg also says that I should be losing LP if i go 1-1 over 2 consecutive ranked games but I go +9.

I feel you. I've been there. -25, +10.

It balances out eventually. Keep winning.

I'm finally doing -17, +20.

I took a month off and then came back fresh. I don't know what changed, if anything, but when I win, I will gain if even.
