There is a definite pattern.
Ones who do not study carefully, apply things gradually, observe themselves and honestly as well as thoroughly then report what occurs consistently do poorly. They often then become bashers and blame the protocol.

It is very easy to discover the truth about this if one takes the time to look into it.
