You've come to the right place if you're looking to improve and I'll have a go at kicking off this discussion.

I would say that it's worth investing 6-7 10nl buy-ins however in a better quality tracker, as you'll easily see a return on that investment at the tables. For instance, you can use the software to post hands easily on this forum using the Hand Converter option here and analyse your own game once you have a better understanding of the stats. You'll also potentially be able to use the HUD stats to exploit your opponents, but again, you'll need to have a good grasp at what the stats are telling you - I personally think a lot of players would be better off not running a HUD when they are starting out as it can be too easy to mis-interpret or be lazy and not generate any decent reads.

When it comes to reviewing stats, it's always worth noting that there are plenty of different ways to beat the games (e.g. I remember reading that Phil Ivey in his online prime used to play a game that generated what was widely regarded as sub-optimal stats). That said, the general consensus at 10nl is that playing a TAG game is going to be the most straight-forward way to crush the games and move up the stakes. If you don't know what thats is, then you definitely need to find out.

The stats you've provided are the basic pre-flop stats and I'm assuming you know their definitions. They indicate that you are a loose-passive player and the general consensus is that this isn't going to be a strong and winning style at any stake. The huge gap between your VPIP and PFR suggests you open limp and cold call a lot, but only open raise your stronger hands. There are a lot of reasons why this isn't a good thing and it's certainly difficult to make much money playing like this. Generally speaking, you want to have the initiative in a hand (i.e. by being the pre-flop raiser) and to be aggressive in good spots, but you'll also want to alter your game based on your position at the table. These aren't short discussions however, so I'd strongly recommend you read the stickies in this forum and get posting some hands - nobody will treat you like an idiot here as long as you have an attitude that is willing to learn!
