Hello,
I'm playing Omaha8 tournaments since the End of April and these are my results (including also stats from the last three years, where I played some times PLO and NLHE Tourneys just for fun while playing cash game).
My winnings are about 7K; I had reached this amount already two months ago but had then a down swing in which I lost about 3K and won it again.
I paste my statistics from sharkscope below.

Which are the most important stats to evaluate whether I'm good or bad?
