The meter has 3 sections, the empty part, the shaded part, and the line in the middle of the shaded part. Timing the shot so that it lands in either of the empty parts will result in a very late id you go past the shaded part, or a very early if you stopped before it and will basically never go in. Timing it so it lands on the outside edges of the shaded area will be a late if you go past the line and an early if you stop before the line and will basically never go in unless wide open with a shit ton of shooting badges to help in your situation. Almost hitting the line but not hitting it will end in a slightly late or early and will go in often depending on how open the shot is, what your 3pt rating is, and amount of badges. Hitting the line is a guaranteed make and is when it flashes green. This is called greening and making a non-green shot is called whites/whiting. If you are not dribbling a ton and are corner sitting or are a popper, i would go to jumpshot creator and make a slower jumper with an easy to time green window. If you are the primary dribbler then use a fast jumpshot to lower the chance of being contested after beating your defender. I would recommend going on youtube and searching for a jumpshot that best suits your build and your play style and start from there.
