Moa Tse Tung was asked what he thought about the French revolution about 100+ years after the fact and he responded with something like It's too soon to tell.

I think the same applies to your question about how good you are. I would say you probably suck. Not to mean or based on anything you actually stated but because nearly everyone sucks after only 5.5 months.

The best comparison I can make is what my sensei told me when I earned my green belt in judo 15 years ago. You know just enough to be a danger to yourself and everyone else around you and not enough to know that you are a danger to yourself or everyone else.

or any even truer cliche: "It takes minutes to learn and years to master."

Judging by your wins you play a few times a month and are going through normal variance but there just isn't a sufficient sample of hands to tell if you are a winning player. If you figure 40 hands an hour for 160 hrs a month (full-time which I don't get the impression you are) you'd have a little over 30K hands played which would be about the minimum you'd need to calculate your winrate with any certainty.

I think a better question for you to ask yourself is do you enjoy playing enough that it is worth continuing to plug away and learn given the neglible wins/losses you receive/suffer.
