So then, right think should be not to include judges who have their own representatives. Ladies judging panel should be for example MEX, NZL, UZB, LTU, BUL, AUT, NOR, GBR, ESP. Mens JAR, PHI, TPE, BLR, FIN, CRO, SVK, POL, TUR etc etc
Something like that - or some pattern where the judges cancel each other's bias. Lets say the top contenders on a given event in ladies are russian and japanese. If there is a russian judge and a japanese judge, russian one will give higher scores to russians, and lower to japanese, and the japanese will do the other way around. On average, it is fine.
Overall, i think the judge's pannel is not the issue, there are enough judges really to make the higher or lower scores given by a single judge mildly irrelevant. The tech pannel is the problem.
