Well, when I started out I walked. WALK WALK WALK!!! You cnt jst start out at any pace. They have to learn the pattern. And it also depends on how well they can flex before hand. It she can bend, flex, turn on a dime, ect. Its probly not going to take as long. And it also depends on the type of bit ur useing. It needs to let them curl their nose in when going around the barrel so that they lift their shoulder and helps them bend. Hope this is at least a lil helpful.
