I think I have the idea to figure this out. What I'm referring to is the alternating of the "J" and "P" walls on the template (included template for reference below). If you have gaps, they don't line up to 7 spots on the wall, they make 11 spots (for lack of better term) of the same size with gaps and walls filling those spots.
I dunno, I hope this helps. The 1 and the 2 are where "you" are, and of course the walls are right angled. Its just the far away wall spots act strange when they have gaps.
