Yes, you are absolutely correct! However, you must pay particular attention to the direction of the wind.....setting your polarity parallel to the wind direction will allow flying much closer to the edge of the window, but only to one side, either left or right, depending on the direction of the wind, i.e., north or south. Setting the compass at either right angle to the wind's direction will allow equal reach to both sides of the window, although to a lesser extent.
Try it, you'll like it!
Is it April yet?
OK I will try your suggestion but there is one thing which might make it difficult, I am in the southern hemisphere so I assume it will all be the reverse or upside down???
I'll let you know.
