I am not really familiar with computerized long arm but I have seen them stitch and its not any faster or slower than a human the only place you will save time is not taking breaks like we humans need. I would guess a crib sized quilt to take about 5-7 hours to do the quilting portion; this would be basic stitching/panto. Remember it takes almost an hour or more to load a quilt and that will count towards your hourly rate. I am sure someone here has a computerized machine that will give better info. Happy Stitching
