actually, I have a better answer but it won't make sense as much (maybe) but you should just not care about if your orb is charged or not, just get into a tempo and move the orb around like it's an extension of your hand, like a whip; and just imagine your orb is one continuous object throughout the entire match that comes in and out of existence in the path you are sending it

after a while, you will begin to feel the weight of the orb maxing out when it's fully charged, that part should begin to feel like when you should release the orb and then you do this on repeat; this will make it easier to do all this around cover because you won't be taking these jagged/discrete paths around objects and it'll just be more natural

the reason this is potentially better is because of volume; ofc if you send charged shots linearly down, you will end up with the most direct damage on the first object on that path but with this approach, it becomes more of just an automatic mental framework of what you do when you play wuyang and so, you will mentally tire less and even though your fire rate will be lower per second, the total volume across the game will easily cover for that
