jwpretd, what if I told you that I invented a fractional aiming system that only involved two hits...a half ball hit and a quarter ball hit. I claim that I can make any shot on the table simply by choosing one of those two hits. I also claim it's a center pocket system, "exact", and geometrically perfect. I also have my own testimonial evidence that the system "works", because I have shot numerous videos of myself shooting balls with the system. I even have videos of my students pocketing balls with the system, showing that it works.In my opinion, the absolute reliance on that first sentence, and the concomitant denial of the validity of the second, is at the root of the acrimony surrounding this subject. Suppose I report results similar to those you posted and someone responds saying, "The actions you claim you took cannot possibly, of themselves, have produced the results you claim."
The person making that statement has said that:
1. I misreported or omitted at least some part of my actions, either inadvertently or deliberately.
and/or
2. I misreported the results I achieved, either inadvertently or deliberately.
Therefore, that person is saying that I'm either stupid or a liar (or possibly both). Even if I didn't overtly analyze the person's statement in the way I just outlined, I might well feel that I've been rather grossly insulted for doing nothing more than saying (rather joyously, as JoeyA points out) "Hey! Lookit, ma! I did this and the ball fell in the hole!"
That's been going on for many years.
Remember, only two shots...a half ball hit and a quarter ball hit...for EVERY conceivable shot.
Now, how exactly would you go about determining whether my claims are true? Do you think they are true? Can they possibly be true, despite all my "data"?
