I'm beginning to understand the purpose and reason as to why the over aiming routine by Woohoojin is so popular. I'm going to drill this in the Range until it can be as smooth and responsive as it could be.
Over aim Warmup
(1) Do the aim routine in slow segments
Over Aim, Move, Confirm, Shoot
(2) Combine the over aim and movement but slow on the confirming. Then shoot
(3) Gradually increase speed to real-time.
If at any point you begin to slip from the rhythm, go back one step.
If you are going at game speed but seem to be flick-missing, slow down just the confirming part.
If you are still not flicking correctly and/or moving sufficiently, go back down to step 1 and do it in slow segments.
