I thought this was an interesting comment, from Pendlay:

Chicken or egg.
Also, comparing Russian to Bulgarian Training (as stereotypes) stuff:
Russian Training usually use percentages of maximum/competition lifts. Typical loading is doubles at 80% or so. Loading is waved very prescribed, so training is highly planned to avoid any over fatigue.
Bulgarian Training usually uses a 'daily max' which can be anywhere within 10% of an all time max, so around 90% ish. Singles are done there followed by back offs at 10% less. Training is not highly planned, over fatigue is prevented by a natural fluctuation. Lifters being lifters they might take weight too heavy too much, so there's more skill involved here.
Basically when put like that, it doesn't look all that different.
