Yeah, I actually looked at the early years today, and in 1969 only the three perfect scores won gold, and in 1970 this was relaxed a little bit, and the overall trend looked to me like there were multiple reforms with gradual relaxation of the standards for gold (although I did not do more than superficial sampling from several time points).
I think the official goal is still approximately 6:3:2:1, but this year those fuzzy boundaries resulted in 67 gold medals out of 630 participants (slightly above 10.6%).
