It is necessary to add an adequate option for the readiness of a heavy shot. At the moment, the arrow starts to glow already at the moment of charging, and not when ready. Also, the charge is not yet ready at the moment the bowstring is fully pulled. I am guided by the creak of the bowstring, but sometimes it is not heard and I shoot with a normal light attack.
It is necessary to make sure that the arrow starts to glow only when the full charge is ready, otherwise it turns out some kind of nonsense.
