Even if you don’t move through the full range, doing the exercise where your muscle is stretched the most (like halfway down in a squat) builds more muscle than doing it where the muscle is bunched...

Doing certain leg exercises that only go partway through the motion—but stretch the calf muscle while lifting—might build bigger calf muscles than doing the full movement or shorter movements.

Lifting weights through a shorter movement range can build muscle just as well as lifting through a full movement range — no difference in muscle growth.

Doing partial-range weight exercises with a longer muscle stretch can build arm and thigh muscles just as well as doing full-range exercises, as long as you’ve been training for a while and do it for 12 weeks.

Doing weightlifting exercises by only moving the weight through the longest part of the stretch actually builds more calf muscle than lifting through the full range or only the shortened part.

Training muscles while they are fully stretched is probably the best way to build muscle size for experienced lifters. Adding exercises that only work the muscle in a shortened position doesn't seem to help you grow more muscle compared to just focusing on the stretched position.
