Just getting started on drill 1 ... the attached pic only has 2 out of the 25 cases, however the 2nd case (as most of the 25 cases) actually has 2 variants.
I colored the 2nd leg, green for Up, red for Down.
Right there, there is ambiguity unless looking "inside" the bar (which is fine with me, but I want this crystal clear as it is the bottom of the foundation).
