Would it be legal to place colored dots on the field where the rings are to be placed to be used as markers for field placement? Such as the pins from VEX IQ? These would just be to assist the field resetters in getting all of the rings placed correctly, and shouldn't affect game play.

Answered by committee
No, this modification is not recommended or legal. We suggest that Event Partners provide printed copies of the color-coded field layouts for Head-to-Head and Skills Matches for each field at the event. These layouts can be found in Sections 2 & 5 of the game manual, and in the article titled "V5RC Field Reset Tips and Diagrams" in the REC Library.
