the optimal solution is no offset at all The faster you fly the more the tail
will pull to the correct side.
Isn't that what you want?
The engine offset is to counter "P" factor during low speed flight, at high
throttle settings, as in take off or a go around. This where "P" factor is
most apparent and air speed and control effectiveness are the lowest. This is so
you don't run out of rudder travel while trying to fly in a straight line the
runway centerline.
At cruise speed, where control effectiveness is the best, the fin offset is
just enough so that constant rudder input is not required. The engine offset at
cruise is of little value, but has little affect on top speed.
