I"ve seen people comment they don't know how fast their arrow shoots! I could not stand it if I did not know the speed of my arrow, weight of the arrow, ect... After I get a bowand set it up, I paper tune and chronograph. If I change tip weight, I'm going to see what effect it made through paper and chronograph. Granted, you don't have to know that information, but I do have to know.
Let's hear from the other equipment detailed chronograping people.
