I just need some professional input seeing my Pattern experience is at best classed as pre-amateur.
From the screen shot you can see that a box that is Ca165m out will give you a horizontal width of Ca 550m.
Now the geometry will dictate the hight. See very basic drawings.
Of course, the lower the height the longer distance we have to execute the manoeuvres.
I understand some manoeuvres will demand extra hight, this is just a generalisation.

Questions: What top of box height is most people using? When you're pulling a vertical 8 is that x2 the hight of the turnaround radius? What point alone the horizontal path would we be pulling to 45deg for the turnaround? At which hight are most of you flying the baseline?
You get the idea:
Look forward to you feedback.
