The rules seem very clear, but I wanted to make sure that my interpretation is correct. In the attached picture there is no elevated robots or goals. This because to be elevated: "2. The Platform meets the definition of Balanced." and the definition of balanced includes "3. Robots and / or Scoring Objects contacting the Platform in their Alliance Home Zone are not also contacting any other Field Elements, such as foam field tiles or the field perimeter." and finally even the black base is part of the platform (https://www.robotevents.com/VRC/2021-2022/QA/818)
Scoring: The blue alliance will not get credit for any elevation, and will only get credit for the mobile goals being in their home zone since the home zone is now defined as a 3-dimensional volume.
Potential DQ: If the red alliance caused the placement of the problem ring at any point in the match, they are also disqualified per <SG3c>: "Per <SG10>, using a Scoring Object to contact the opposing Alliance’s Platform during the last thirty (30) seconds would be considered a violation of this rule." since "Violations of this rule which do interfere with gameplay, such as preventing a Platform from becoming Balanced, will result in a Disqualification, regardless of whether the interference was Match Affecting or not." and it prevented the platform from meeting the definition of Balanced. This happens whether there was intent or not (https://www.robotevents.com/VRC/2021-2022/QA/842)
This would obviously be the same for any mobile goal touching any part of the platform even though it has zero impact on the alliances ability to elevate.
