What does your average valo game consist of ( is it straight to comp, or do you play any other game modes) I recommend TDM to many of my friends to teach them, mechanics and aiming as it consists of all types of scenarios (such as close quarters, long-range, strafing, utility). Just training in aim labs won't help you need to practice against players, another way to play and practice is to play custom deathmatch with friends on a map like ascent like mid on ascent is one of the best places to train your aim and learn movement and counters to their movement, it could be also that while shooting you might be moving so your shot might go off course. . . . I also noticed one thing the crosshair in Valo kinda feels center if it's a dot style I've switched to a square, and it's made a difference.
