Now, go ahead deny Hal claimed he gave Efren lessons.
I am guessing you didn't watch the video. Stan was relating hearsay and being clear to say that there is no direct evidence for anything concerning Efren and Hal.
You know Efren, do a video call and ask him directly and report his answer.
I can tell you that when Hal and I met he demonstrated several ways to aim and attached several pro names to them. I, of course, had no way to verify any of that information. However it was not even relevant for me as the only thing I was interested in is whether Hal could teach me something that was of benefit to me. And he did exactly that as I have related several times in this forum.
In the video Stan is speculating, based on observation related to him, that Efren was aiming in a way that appeared similar to cte. He further postulates that the motions of a lot of top players suggests that they also use their vision in a way that produces similar structure to what is produced when a person uses cte. He further suggests that down the barrel aiming, or what is being asked of ghost ball users is actually not what most pros use.
Obviously without some serious study, interviews and examples such a statement cannot be given any validity outside of the speculation context in which it was offered.
In the thread I found easily, contrary to your claims of being difficult up look up older threads, the question of whether Hal directly taught Efren anything was addressed and answered quite clearly.
However nowhere was it claimed by Stan that Efren went to Pennsylvania directly to learn from Hal as you claimed. Maybe someone somewhere claimed that in error but it has not been a central claim in cte that cte users and students are being told as a matter of course.
I can see however that you are addicted at this point to your quixotic attempts to discredit CTE. I apologize for not realizing that you are a sick individual who traded one junkie habit for another.
I hope you find peace.
