I had an inconsistency issue when I was a teenager tracking an EP in my first studio expereince. The recording engineer came into the tracking room with a red Sharpie, drew an X on the center of my snare, and said, "hit only here." It worked.That wear pattern on his snare batter: all them stick marks in a tight small area,
I interpret that as a sign of good technique and consistency.
I've seen kits on which some drummers hit the batter all over the place
instead of concentrating their stick attack as dead center on the head as possible.
From that point on, I developed an extremely consistent snare hit. In fact, a few years ago I had an album remotely mixed by a multi-platinum awarded engineer who's been in the biz for the past 30+ years. He emailed us, saying, "The drummer on this session is hitting his snare incredibly well! Very consistent player!"
