Your Tactics Trainer rating appears to have gone up quite a bit over the last 30 days. Maybe you're getting better but doing tougher tactics exercises.
improving tactical vision

coffeethyme has a good point, perhaps the puzzles you are doing are getting tougher. Is there a level of difficulty attached to the puzzles? I don't have the statistics option so I can't check.

You could hammer the tactics courses over at the ChessMentor. I recommend GM Patrick Wolff's courses especially since he breaks it down by motif. Because of the time pressure, the TT is more of a way to test yourself. I think studying tactics over at the Mentor might be more productive. Hit a course on say, forks, real hard for a few days. Get every lesson up to 100%. Pick another course and repeat. After a few weeks go back and review those courses. Still 100% ? Probably not. When you can go through the ChessMentor courses at a good rate, then go hit the TT again and see if you've improved. Good luck!
I have been cracking down on chess for almost a month now. I do about 50-100 tactics trainers per day and still get only half of them correct! Am I missing somthing? Is there somthing more than practice that I can do? ( Im doing chess mentor and watching videos) please help! thank you :)
