There would have to be the optimal COMBINATION of acceleration and length of batpath. The batpath would have to be circular or hooking or there would be disconnection from the power source (por transfer mechanics interrupting rotational component of swing) and therefore lack of adequate acceleration and most likely deceleration before
contact.

During unloading/rapid bathead acceleration in a power swing,there would have to be an arc in the handpath in a 2d plane roughly perpendicular to the spine because of these other messy body requirements which can be more simply though of as a series of arcs as Jack describes them.

If you want to straighten the path you can try a placement swing or if you taker shortening to an extreme, you can bunt. Even though acceleration is low in this case and timing error is high, the bat is in the zone long enough to tolerate a big timing error, but, these are different skills, not a power swing with good average.
