As Johny8984 pointed out, 14 tournaments is not enough to draw many conclusions either from your results (green line) or your luck-adjusted results (red line).
If you play 1000 tournaments with a 50-30-20 structure, you have strong statistical evidence that your true ROI is within about 10% of what you observe. That is still not very tight, and 1000 tournaments will take a long time to play if you are only playing 1-4 at a time. If you look a the red line you get a similar level of accuracy after only about 500 tournaments. However, there is still a lot of luck which is not seen by the luck adjustment. If you have KK vs. AA, or AA vs. KK, and all of the money goes in, it's just luck whether you had the aces or the kings. However, the red line doesn't see this luck. In effect, it assumes that whatever happened before you got all-in was intentional.
In the short run, it is better to focus on whether you are playing well. Were you paying attention to the stage of the tournaments, your stack size, and your position? Are you making decisions which reflect what you studied? Were you observing your opponents? It shouldn't take 500 tournaments to see whether you are comfortable playing or not.
