The ICPC Regional Rules for Regionals (https://icpc.global/regionals/rules) mention that a participant may not meet the age requirement and yet legally compete if certain conditions are fulfilled.
The rules state: "The coach must demonstrate that such an extension would not provide an unfair advantage to the team." However, in the NERC, we have a 32-year-old participant who has 10+ years of experience in coaching and who takes an active part in ICPC-related activities: preparing contests, participating in the Petrozavodsk training camp, etc. How is he eligible? Which part of the rules am I misunderstanding?
