Rule <SC1> states that referees should avoid moving Scoring Objects while evaluating scoring statuses, and that if an object must be moved, its status must be agreed upon by all Teams and the Head Referee and recorded before it is moved.

After a Match ended, but before the score was determined, a referee accidentally knocked over a Goal stack while inspecting an unrelated interaction. The statuses of the displaced objects had not been recorded.

Is this situation grounds for a replay under <GG5>, or should the Head Referee determine the score from what was observed by themself and/or scorekeepers? If the Head Referee calls for a replay but the Event Partner does not agree, what is the outcome of the Match?

Rule <GG5> states that a Match replay “must be agreed upon by both the Event Partner and Head Referee.” Rule <T3> states that “Referees are not permitted to review any photo or video Match recordings when determining a score or ruling.” Rule <T1> states that Event Partners “may not overrule a Head Referee’s gameplay or Robot decisions.”

When deciding whether to agree to a Match replay under <GG5>, may an Event Partner review photo or video recordings of the Match? If so, may the Event Partner share what they learned from the recording with the Head Referee, given that the Head Referee may not review recordings under <T3>? If the Event Partner can review video recordings, but cannot share what they learned from the recording with the Head Referee, what is the appropriate outcome if an Event Partner cannot agree with the Head Ref regarding a replay decision? Does the answer change if the recording shows something that occurred after the Match ended but before the score was determined?

Point a-v of <GG5> states that a valid reason a match replay is (emphasis mine):

Field control disconnecting or Disabling multiple Robots. Note, this is sometimes confused with a Robot whose motors have overheated, or bent pins on a controller’s competition port causing intermittent drop-outs. In general, any true Field fault will impact both Alliances simultaneously, not one Robot at a time.

The red box below the rule states:

Note: Communication or control issues affecting a single Robot are not considered eligible grounds for a replay.

Suppose that a single Robot experiences a field disconnect during a Match. That Robot is the only Robot affected by a disconnect during the Match. After the Match, the Head Referee examines the Smart Field Controller and determines that the disconnect was caused by bent pins in the port of the Smart Field Controller (in other words, the disconnect was caused by an issue beyond the control of the Team). The Head Referee is sure that no other issues with the smart cable, Controller of the affected Team, or their Robot, could have caused the disconnect. Is rule GG5 stating that the Match should NOT be replayed?

Looking for calarification on GG5. In a Skills Attempts when a suspected Field control disconnect has "Disabled Robots" - there are no other robots to check for movement per GG5. When a robot disconnects or pauses during a skills run unexpectedly, should the team be given a replay attempt? Thanks

<T5a> Field Element tolerances may vary from nominal by up to ±1.0”.

On long goals for push back, tape is applied manually to define the control zone and may be applied onto goals by young and inexperienced volunteers like children. When taping the long goal control zone, I could see someone starting in the correct spot on the top of the goal (when fully assembled) but wrapping the tape around the goal in a way it slants away and back to the initial correct spot. In this plausible scenario, the long goal control zone would not match figure CZ-1 in Game-Specific Definitions. This brings up the first question,

1. Does the entire tape line define the planes to the long goal control zone (such that the control zone would not be confined to two vertical projections perpendicular to the field) or does just the outermost, correctly-aligned tape at the top of the long goal (the corner of the goal in this example where the volunteer started to apply tape) define the projections to the long goal control zone?

<GG5> Match replays are allowed, but rare. a. Match Affecting “Field fault” issues. i. Field Elements starting in incorrect positions, and out of the allowed tolerances (see <T5><T5>).

<G3> Use common sense. When reading and applying the various rules in this document, please remember that common sense always applies in the VEX V5 Robotics Competition.

If the first question is the first answer and the applied tape for the long goal control zones appears off to those scoring the match (we are assuming the head referee(s) is here to keep calls like these consistent across an event), what should be done in the following,

2. The tape is with the 1" tolerance but is substantially offset (such as 3/4" offset, the entire width of the white tape itself) such that it has changed the state of a block being within the long goal control zone. The tape as is would not give benefit of the doubt the block could be in either state, it is well within one of the states inside or outside the control zone. The tape as it is defined in CZ-1 would give benefit of the doubt and decrease the certainty of calling the block in one state, the tape is not set for the referee to give benefit of the doubt for where the tape should be. The situation could also be flipped such that an unclear call would become clear when utilizing CZ-1's tape lines. Should the block be scored as is defined by the tape due to <GG5> or can <G3> be applied in egregious instances of tape technically within tolerance?

3. Take the same situation as 2 above but the tape is outside the 1" tolerance. Should the block be scored as is since the field has been that way all day, can <G3> be applied in verified instances of tape outside tolerance, or is a match re-play after fixing the field long goal tape lines required, not allowed, as outlined in <GG5>?

4. Does situation 2 or situation 3 apply differently if the scoring decision in question is match affecting?
