Maybe you can help solve what's happening. The INTERSECTIONS ON THE SHALLOW RED LINES are producing good hits. Look at the frequency. The purple right angle below(as a reference) is the right angle that is being used to go down then up (creating a right angle 90 degree relation. I did another grid in "my published" like this. Some of you that took drafting may have a clue what's happening. Does this have anything to do with cross-hatching or something in drafting? It's interesting the way the grid does NOT change spacing, but produces many significant hits. Otherwise...not random.
