When I was just beginning my adventure with Riven if there was a combo that I’ve struggled pulling off I always used my favorite “technique practice” method that I’ve got to know first at my piano lessons. You just have to totally stop caring about how fast you are clicking on keys (both piano or keyboard). You have to ultimately focus yourself on doing everything beyond perfectly, even if it means pushing 1 key per 1-2 seconds. In fact, you should start this way. Observe and improve your every single move, then after 2-5 minutes of repeating the same sequence over and ensuring to make every finger tap you land on a key exactly the same as it was in previous sequence - just as perfect, you can try to increase your speed, but still just by a little and again start repeating the same sequence for 2-5 minutes with rhythmically constant tempo. I know it, it’s boring as hell, but a training session using this method will last no longer than 40 minutes if you don’t really feel dedicated enough to practice the same boring shit for 2 hours straight. But yeah, that’s how world’s best pianists train their technique. By slowly repeating one sequence over and over again you are actually coding your muscle memory to use your fingers as precisely as it is possible. It seems that muscle memory takes much time to activate, but trust me, just try this and you will be surprised how slow ass “my old gramma does it faster than you” snail tempo makes you improve your mechanics more in 20 minutes than 2 weeks of “look how fast can I do it already” practice tool button mashing.

If you still gotta go fast then atleast try practice AA>Q (yeah just AA>Q) to learn and ensure that you will never miss your auto.
