 - A6e+) [CLARIFICATION] If the puzzle falls into the lap of the competitor after stopping the timer, this is considered touching the puzzle.
 - A7c+) [ADDITION] If a result signed by a competitor is found to be incomplete or unreadable, it should be interpreted the worst reasonable way (e.g. "1:05" will be considered 1:05.99, "25.X3" will be considered 25.73 if X could be either a 1 or a 7). Given that the Stackmat timer displays a time of X:0Y.ss as X:Y.ss, a missing tens digit should be considered more likely than a missing ones digit (e.g. "1:2.27" will be considered 1:02.27). The judge who signed an ambiguous result may be requested to clarify it, at the discretion of the score taker.
+- A7c6+) [EXAMPLE] Examples of signatures that identify the competitor: Name, initials, WCA ID, competition registrant ID, a reasonable nickname.
+- A7c6++) [EXPLANATION] A competition registrant ID is an identifier (e.g. a number) assigned to a competitor for the competition. Some competitions use this to keep track of score sheets and enter results.
+- A7c6+++) [RECOMMENDATION] The organization team may request competitors to sign with one particular method of identification (e.g. competition registrant ID), but competitors should not be disqualified for using a different method when signing.
+- A7c6++++) [ADDITION] Competitors should use the same signature when they are judging and/or scrambling at the competition.
 - A7g+) [EXAMPLE] Examples of incidents that could grant a competitor an extra attempt due to inexperience: not waiting for the green light, improperly starting or stopping the timer, going over inspection time due to misunderstanding how to start a solve, or other procedural time penalties.
 - A7g++) [CLARIFICATION] Individual penalties cannot be waived. A full extra attempt must be granted.
 - A7g+++) [RECOMMENDATION] The WCA Delegate should use stronger discretion when granting more than one extra attempt to the same competitor. If more than one extra attempt is granted, it should be for a different type of incident. Example: if the WCA Delegate already awarded an extra attempt for a competitor who did not wait long enough for the green light, they should not award another extra attempt if that competitor fails to wait long enough for the green light again.

 - E2b+) [CLARIFICATION] A competitor may choose to stop an attempt early by handing in a solution before the time limit.
 - E2c+) [CLARIFICATION] Although the judge may provide a standard sheet for competitors to submit solutions, a competitor may submit a solution on a different piece of paper. (Note that the piece of paper must come from the judge, according to [Regulation E3a](regulations:regulation:E3a).)
-- E2c1+) [EXPLANATION] A competition registrant ID is an identifier (e.g. a number) assigned to a competitor for the competition. Some competitions use this to keep track of score sheets and enter results.
 - E2c1++) [ADDITION] If the competitor forgot to write information to identify the attempt on their intended solution paper, they are permitted to add it in front of a judge after the time limit. In this case, the competitor must ask the judge while submitting their solution and then immediately write information to identify the attempt (without making other changes) under direct supervision of the judge. Once a competitor has finished submitting their solution (e.g. placing it in the judge's hands and allowing the judge to move on to the next competitor, placing it on the judge's table and walking away), they are not permitted to add any information. If the competitor writes anything after the time limit but before asking the judge, the attempt remains disqualified (DNF).
 - E2c1+++) [EXPLANATION] The competitor is not required to write the competition name, round, and/or attempt number on their submitted paper, but may wish to do so in order to help the organization team keep track of submitted solutions.
 - E2c1++++) [ADDITION] If a judge finds a submitted solution without information to identify the attempt (e.g. while grading the attempt), they should find out the competitor who wrote the solution in order to assign them a DNF (rather than DNS). Note that the competitor must not be allowed to write information to identify the attempt at this point, so they must receive a DNF result.

         - A7b1) If penalties are assigned, the judge records the original recorded time displayed on the timer, along with any penalties. The format should be "T + X = F", where T represents the time displayed on the timer (the "original recorded time"), X represents a sum of time penalties during the attempt, and F represents the final result (e.g. 17.65 + 4 = 21.65).

The competitor is ultimately responsible for ensuring that they and the judge have signed an attempt.
