 - 4d+) [CLARIFICATION] Some puzzles use standard color schemes, except that white is replaced with black. In this case, black is the darkest color and must not be treated as white.
 - 4d++) [ADDITION] It is permitted for the puzzle to change its orientation when it is moved from the scrambler to the solving station, as long as no one is attempting to influence the randomness of the orientation (see [Regulation A2e1](regulations:regulation:A2e1)).
+- 4f+) [RECOMMENDATION] The WCA Delegate should generate sufficient scramble sequences for the entire competition ahead of time, including spare scramble sequences for extra attempts.
+- 4f++) [REMINDER] If the WCA Delegate generates any additional scramble sequences during the competition, the scramble sequences must be saved.
+- 4g+) [RECOMMENDATION] After verifying the puzzle is scrambled correctly, the scrambler may pass the puzzle to another scrambler to verify. In this case, both scramblers should sign the scorecard.
 - 4g1b+) [CLARIFICATION] For 5x5x5 Blindfolded, incorrect puzzle states must always be corrected.
 - 4g1b++) [RECOMMENDATION] The WCA Delegate should use stronger discretion when determining whether or not incorrect puzzle states for 5x5x5 Cube need to be corrected.

 - 11e2+) [ADDITION] If an extra attempt itself leads to an additional extra attempt, the competitor should keep doing extra attempts until there is a valid extra attempt to replace the original regularly numbered attempt.
 - 11e2++) [EXAMPLE] Suppose a competitor has 5 regularly numbered attempts, and #2 leads to extra attempts. The competitor should do extra attempts until there is a valid extra attempt to replace #2. Suppose later another attempt leads to extra attempts, the competitor should proceed in a similar way as for #2.
+- 11i1+) [RECOMMENDATION] Competitors expected to meet these criteria should have their scrambles checked by a second scrambler before being sent out (see [Guideline 4g+](guidelines:guideline:4g+)).
+- 11i2+) [RECOMMENDATION] If the WCA Delegate is unsure whether or not the incorrect scramble provided a significantly less fair outcome than the original scramble, a provisional extra attempt should be granted.
+- 11i2++) [REMINDER] Although individual results achieved on incorrectly scrambled puzzles may be allowed to stand, the WCA Delegate must ensure that incorrect scrambles do not become common.
+- 11j3+) [REMINDER] The scramble sequence used for the extra attempt must not be obtained from a previous group.

 - A2c2+) [REMINDER] If the competitor accidentally views a scramble they have not yet received, the competitor must not receive that scramble for their own attempt and an extra attempt must be granted instead.
 - A2d1+) [ADDITION] If the scramble signature is found to be missing before an attempt, the puzzle should immediately be returned to a scrambler for verification and a corresponding signature.
-- A2d1++) [ADDITION] An attempt must not be disqualified solely due to a missing scramble signature. If a scramble signature is missing after the beginning of an attempt, the judge must allow the attempt to continue (if it is still in progress) and the WCA Delegate should allow the result to be kept. However, the WCA Delegate may replace the attempt with an extra attempt if they have a reason (other than the missing signature) to suspect that the scramble was incorrect.

 - A3c3+) [CLARIFICATION] The competitor may reset the timer before/during the inspection phase if the judge accidentally neglected to do so. However, it is the responsibility of the judge to make sure the timer has been reset (see [Regulation A3b](regulations:regulation:A3b)). If the competitor accidentally tries to start the solve with a timer that the judge did not reset (i.e. the competitor performs inspection, places hands on the Stackmat timer for a reasonable length of time, assumes that the timer will start normally, and starts to operate the puzzle), the attempt should be replaced by an extra attempt, at the discretion of the WCA Delegate.

 - 11h) A WCA Delegate may require competitors in serious violation of [Regulation 2k3](regulations:regulation:2k3) to leave the competition venue, taking into account the seriousness of the situation and the best possible course of action. If the competitor refuses to do so, they may face disciplinary action in the WCA.

Exception: the WCA Delegate may grant an extra attempt at their discretion if they believe this provides a significantly fairer outcome (e.g. the incorrect scramble received was extremely easy and the competitor achieved a new personal record, the incorrect scramble impacted the podium for an event, or the puzzle was deliberately scrambled incorrectly).

+    - 11j1) If the competitor believes they received a duplicate scramble in inspection, they should stop their attempt and call over a WCA Delegate without applying any moves to the puzzle. A competitor should not be penalized for incorrectly reporting a duplicate scramble genuinely, at the discretion of the WCA Delegate.
