/\ This.Culture and context matters, and you can't copy pasta Warsaw Pact methodologies (or Chinese methodologies) to American weightlifters, who don't have the same motivations or grow up in the same system, and expect the same results.
Two interesting side notes:
1. My coach trained in Cuba under the Soviet system. He said when the Bulgarians came for a visit, lots of the Cuban lifters were enamored with the "Bulgarian System." Those who made the switch, burned out and never recovered. That was the danger, the gamble, he said.
2. Pyrros Dimas, and Kakhi Kakhiashvili, both 3X Olympic Champs, and 4X Olympic contestants, trained under the Soviet system, competing for the Soviet Union. They then switched/fled to Greece and competed for the Greek team, which had a Bulgarian influence. Dimas has publicly said he thought the Bulgarian way of training was superior, but probably couldn't have survived training without the base that the Soviet training gave him.
So, take what you will from that.
