At the end of the game one red robot is hanging at A tier, and the second red robot is attempting to also climb to A tier. Blue accidentally violates <SG11> and prevents red from hanging. Neither blue robot elevates. So the red robot gets 20 points for an A tier hang.
The game finishes with blue winning by 17 points. To determine if the SG11 violation was match affecting we look at the game manual.
...then it should be assumed that they would have reached the highest possible Elevation Tier when determining Match Affecting implications.
So we give a J tier hang to red (20 points), along with their existing A tier hang (now 15 points). Using this criteria, the violation would not be match affecting, as Blue still wins by 2 points.
However, if red had 2 robots at A tier, then they would get 20 points for each robot, and would have won the match by 3 points. Should the accidental SG11 violation be match affecting in this case?
