I had a Russian coach who described the Soviet training philosophy similarly.

(In a Russian accent) “if you throw many eggs at wall, most will break, but those that don’t are strong egg. Igor was strong egg”

He had multiple top 10s at world championships and 1 medal… definitely a strong egg

This exactly reminded me of the Bulgarian Weightlifting System. You get a large group of students and put them through a high-frequency and high-load system that breaks nearly everyone.

Whoever survives to the end will be a world champion.
