I think this is a good idea, in theory. But, I am also a huge fan of incremental improvements. If you go and try to fix every leak you find over 30 days, all at once, you are going to be biting off a whole lot. It might be more than you can handle.
Taking a week off is a good thing. I do that. During that week, focus on finding a weakness or mistake that is common in your game. Then, I would start playing while actively working on fixing that class of mistakes. Maybe play a little less, but work on bringing that part of your game up. Then, in your off time, keep looking at your old hands and the new ones you are playing. Once you have found a different type of mistake, and feel like you've improved on the old one, you start actively working on fixing that next one.
You do this while you play. It makes it a lot easier. This is how we learn anything. I am not a good Omaha player. And, I realized that a big mistake I was making was focusing on fixing all my errors at once. I was trying to improve everything at the same time. Instead, I was not making progress on any of them. Since that time, I have decided to focus on a very narrow subset and improving the mistakes I was making there. In particular, I was/am playing too loose out of position and not focusing on the whole pre-flop to flop situation. That's a big leak in omaha, as certain hands lose or gain value based on a bunch of pre-flop factors which translate into flop scenarios.
I know there are weaknesses in other areas of my game. But, I am making much more progress by working on this one first. I still try and avoid mistakes for other areas, when I play, but I am focused on this. I watch my own hands for these things and my opponents' hands. Because I am working on just this part, I find it easier to improve on it. When I was aware it was a problem, but was trying to fix 10 other things at the same time, I wasn't actively focused on any of them enough to make progress.
Incremental growth is a process. And, part of that process involves practice and incremental improvement. If you skip the practice, you have all the information in your head, but you will be drowning in too much at one time when you play.
I hope you get what I am saying. If you still decide to take 30 days, that is great. But, I would stress finding one or two things that you consider your "biggest" problems and work on fixing those first when you come back. You can be aware of other areas, but really focus and grade yourself on your growth in those specific spots.
