I bought an actual stand alone metronome for this exact purpose a while back on a whim, but never actually used it because I was over complicating things. This re-inspired that idea because I want to improve, so, thank you.
I’m also a ‘careful’ aimer with roughly the same scores as you in each of the areas in Kovaaks. While the VT community disgusts at the idea of using a metronome, I’d say it’s a great speed pusher if we don’t overuse it.
It isn't something to go hard on. Just something to push yourself when you get "stuck" on being lazy. Why I mentioned it also as a downside. You will have no variation of hitting the close target and the target further away. But its only to create pressure in a new way. Remember: Why I limited its application but it did help once I removed it.
The aim breaks down into 2 modes for me. Long arm shots and close wrist clusters. Use the metronome and only use arm mode. If you save time on the long shots after a week of practice. Your still winning. You need to periodically chase scores and use mixed technique if you want total aim development. Think of gym training. You can target a muscle group or do a 4 week cycle of heavy/volume wateva then take a few days rest of light training then go back to your main goal. Use same idea here.
Try this just track clicks, if your highest ever clicks per minute is 100, right. NOT score. Then just try and do more if your doing 115 but you missed alot so your actual score is 91 becaused you missed an awful lot. Then who cares your actually faster. If you hit 115 clicks missed a buch of shots so your score got downgraded to 91, remember all those misses wasted time which means your true bpm would be 120 or 125. Push the speed then discover the control needed for that speed. There is a balance to this but it works.
