The past thoughts were finger shooters needed longer wheel to wheel length bows which were more forgiving for finger shooter. The reason is finger pinch angle. A long bow has greater string angle thus less finger felt pressure. Short bows tight string angle. These thoughts started with recurve bows and naturally followed into compound bows. Used to be a 41" axle to axle was just about right for finger shooters then a 38" bow was considered a long bow now 36" would be considered long. If you ever shot a short recurve vs a 64-66" recurve the finger issue would be very clear.
