You have shown 4 sections with a maximum elevation of 512 units. You could have done the same thing without joining them. Why do you think you have to join them? The maximum elevation per section is still 512 units, or 45 degrees. To exceed the limit you would have to show 3 sections of greater elevation. It's possible to have 2 sections exceed 45 degrees, so that doesn't count.
