Ranked play frequency, affects lp gains/losses [Possible bug]

Has anyone else noticed that the more often you play games, the more it affects the lp gains and losses?

Longer explanation:

So back when I had a win rate of about 53%, I noticed that (regardless of win/loss rate) if I played say 10-20 ranked games in a given day, i would eventually lose more lp for losses than wins, but if I only played 2-3 games a day, I would gain more lp than I lost.

Has anyone else experienced this?

it seems like if I play a lot of games back to back to back, i would lose around 20 lp a game and only gain around 15-18 a game. But if I didn't play for 3 or for days in a row, come back and play, then I would lose and gain about the same amount of even gain for from wins than i lost for 4 or 5 games or so. then it would fall back in the pit of losing more than gaining.
