There are better places to focus your efforts and concentration, but there's nothing this graph is going to tell you that you can do to make yourself a better poker player. Honestly what I would say is not to worry about it.
But just because you had a few tournaments running under expectation early it doesn't guarantee that you're going to catch up later - in fact, if you ran at expectation continually from here on out the gap between the adjusted results and the actual results would remain steady as it is. Especially with the chips expected graphs you're more likely to see big swings when you play in MTTs because late in the game you can win or lose a whole lot of chips - especially if you've switched to SnGs or something since. If you look closely what you'll see is that you had a few tournaments where there were big swings (especially with chips) and that the distance has stayed relatively consistent since that time.
