Me too. Sometimes what feels like slowing way down takes a whole 0.1 or 0.2 seconds per shot, but it is hard to make yourself take that tiny bit of extra time. Others talk about shooting according to what you need to see & I think that is the trick, making yourself see a good & stable sight picture as needed, but it is hard.
I'm thinking that maybe I need to back off practice for IDPA specific stuff & spend more time on fundamentals. Dry fire & shooting plate racks or tin cans or any other reactive targets with focus only on hitting and not on time.
Other thing is that shooting with warp speed folks like DD & TJ & etc creates a sense of time pressure that is a bad thing. These people are evil!!
I concur with everything you just said, doctor.
