Struggle break even on PLO Zoom on GG

Hi, I'm recs player trying to grind PLO Zoom (start lowest 0.01/0.02) on GG for a year.
Since this project started, my goal has been to grind 100$ to 1000$ (including promotion).

Now a year and a couple of months past then, I'm trying to evaluate the progress.
I'm trying to improve my game because when I exclude GG's promotion, my graph seems to break even
after playing around 70k hands.

Any suggestion ?
Should I evaluate the game with or without a promotion?
Is 70k hands an adequate sample size?

PS. The graph shows my local currency.

WITH PROMOTION

WITHOUT PROMOTION
