Most dimensions here look like a designer draw curves that looked good, and the person creating the drawing told their CAD software "put a reference point every 0.5mm of this curve". The mold manufacturer will ignore this part of the drawing, and tell their machine "follow the curve that's in the production file, with tool X at speed Y etc".
