Hi everyone,
I have a general question about PPT. PPT is discussed in the forums relating to HBP/PE3 and sPL/PE5. Why is it that the formal PPT progression element is not introduced sooner than HS/PE9>iM? It seems that PPT is a fundamental element for early HBP and sPL progressions. I'm curious because given coach Sommer's methodical approach to GST, there must be a reason for waiting to introduce PPT until HS/PE9. ...anyone know why?
