I didn't read the whole thread, but I watched your video. The ghost is a measure of a good player, but not a great player. A solid A speed player should beat the ghost well over half the time. Something like a 680 Fargo. It sounds like you might be in that speed range.
Were the balls used in your video also new? They look like brand new Aramith Tournament Set. My best Ghost performance by far was I won 7-2. I did it with old Simonis, but brand new out of the box Cyclop balls. Using the new balls was almost like using brand new Simonis. Having both brand new, I can only imagine how the balls rolled.
A TOP Pro, Neils, beat the 9 ball ghost something like 100 games won to 20 games lost, on video. I believe he did it on a broken in table and old balls.
In summary, us lesser players love when we beat the ghost once in a long blue moon. For you, you should switch to the "Pro" 9 ball ghost in our thread, or the 10 ball ghost
