LP Gains / losses seems off in Gold 2 - 4

Gaining 20 - 21, losing 16. But my account is not on a huge win or lose streak I'm just sitting in mid gold with a 48% WR 200 some odd total games. I know I would be higher rated if I played my one trick. I've been low to high plat since season 5 and even in Season 9 peaking plat 2 briefly. Any thoughts on why it would seem I should be climbing when clearly 48% WR I am just boosted. It's been like this since I made the ACC originally gaining 32LP and losing 12, but now still 48% WR gaining more than I lose , harderstuck😋,
