Hey guys, I am low stakes PLO grinder at stars (was grinding at PLO5 and moved recently to PLO10)

While I was analyzing my graph by using pokertracker, I found that my "money won without showdown" is relatively highly negative. (It just linearly drops down)

Do you guys have any tips to improve that stats? (should be really different to the case of holdem)

I attach my PLO5 and PLO10 graphs.

Thanks!
