I only use my paper targets for dryfire (I'm a cheapo).
The rest of the time it's rimfire on steel for me! 25 yards, little poppers seem to be good enough for accuracy training. About a week or 2 before a match, ill bust off some 50 yard bill drills with rifle, and long range training.
Aside from whatever the particular drill is, I find as long as I practice at all, the better my match performance will be. Your drill looks fine, just more leg work than I put in.
Oh, I also practice one shot transition drills (twice the transitions for the $) ha ha!
Keep on shooting, mix it up with some different stuff from time to time. Find your weakest spot at the last match, and work on it. That is what my focus is on in general, while practicing.
