Could they not at least identify which bullet points they used to award GOE levels. I would imagine they all understand those and could say for example...
2A-3t-2t +2 GOE. Bullets satisfied (1,3,5)
I would imagine a two to three sentence explanation for PCS marks should be achievable even if in their own language. Translated upon request by an ISU translator. I would imagine they are already there in mass. You could only do it for the last flight and upon request and subject to approval after that if necessary. You could establish a point barrier within 3rd place that automatic gets the explanations for tight fields going 8 places deep.
