Training standards and drills

For those of you out there lucky enough to be able to draw from concealment what drills are you running and what time standards do you use? Personally I use a half sheet of paper as an a zone and 5.5x5.5 paper as a head box target. I do all my shooting from concealment and start with some single shots then work into doubles then some failure drills. For first shot I try and stay under 1.5 but have been able to drop just below 1.4. For two shots I try and stay under 2 seconds and closer to 1.75. Failure drills I’m coming in around 2.3. What other (non ammo draining) drills should I be doing? Am I holding my self to good time standards?Edit: I pretty much always shoot at 7 yards. Will back up to 10 for some. As for the rest of the target I shoot at a 18” wide cardboard that is 5’8” tall and place the paper a zones at what would be my center mass and head standing right in front of it. via /r/CCW https://ift.tt/3mFUWRy
