I'm in the shooter dog house today too. I went out and sucked it up big time from the 25 yard line. I kept hitting high and left, and I know I'm anticipating recoil. When I ran dummy rounds through a few drills I could really see it. It's pretty aggrevating to get in a slump, but I know what I need to do to get out of it. For me, knowing what's wrong is the biggest part of the battle.
It sounds like you know what's wrong, I would concentrate on trigger pull if I were you. You might be mashing it a little. Friday I'm going to do a bunch of dry firing drills. Saturday I'll do some five and one drills from 25. Then I'll shoot some one inch dots from the 5 yd line. Then I'll draw and fire two rounds from the holster at 25 a few times to see if it helped. Maybe a little weak hand shooting will help.
Don't worry about what target you use too much. The diagnostic target is just that, it's a diagnostic tool to use until you can start correcting your technique on your own. If you know what's wrong you can fix it. Dry fire practice would probably be a good idea. Keep drilling with the snap caps. They help show flaws in your technique and they let you practice malfunction drills. Even when I'm shooting well I like to throw in a few snap caps to practice malfunction drills.
Keep plugging away, bad days happen, but even a bad day at the range is still a good day. When you get "on" it really feels good.
