Examples that can result in disqualification, at Delegate discretion:
Intentional +16 penalties (makes it hard to judge properly, even for the most experienced judges)
Intentionally poor FMC results (can waste solution checker time)
Intentional redundant moves in FMC (can make it harder to read for solution checkers)
Intentionally letting timer run to get poor results (unnecessarily wastes the judge's time and takes up a station)
Intentionally doing many redundant or non-productive turns to get poor results (same reason as above)
Solving a puzzle that the competitor does not know how to solve (same reason as above)
Solving a puzzle without knowing enough algorithms to solve it every time (e.g. not knowing a Square-1 parity algorithm and hoping for a parity skip every solve)
Solving a puzzle while imposing unnecessary restrictions (e.g. solving one-handed or blindfolded in the two-handed 3x3x3 event)
Non-examples that should not result in disqualification:
Competitors who aren't among the fastest at an event, but are trying to the best of their abilities
Competitors who aren't among the best FMC solvers, but still put good effort into their solution
