I think there is a lot be to said for don't suddenly dramatically change your behavior.

So in running there is a 10% ie rule don't increase mileage by more than 10% per week.

As the body adapts then mileage can be increased more safely than just running til you fall apart and injury results.

So the deep squat camp will say we have always done it like this.

Shallow half squat camp say its safer but it is the contradiction and justification that is what I was curious about.

Thanks for the great reply. Chris
