Thank you for taking the time to do this and reporting your results. There's always multiple ways on these wwyd's and putting them up is a way to see into other peoples minds. Personally I enjoyed all the thoughts that were put up here.
I, myself, usually test my ideas before posting.
Thank you Frank, for this scenario!
This was the first time I ever actually worked on a shot, it was very informative!
As I said, I thought that hitting the 12 anywhere near the center facing toward the rail , would probably scratch.
I started thinking some more after my first post and I went down and just shot the cue ball at the angle it takes after the first rail into the 12 to see if it actually was a high % scratch and I had gotten lucky, with only 10 shots.
At any where near pocket speed, I could not get the ball to scratch even trying!
It either kept hitting the ball extremely thin , or it hit a little fat, and double kissed out,and down, toward the bottom rail.
What I think is happening is that at slow speed , the ball does not compress the cushion much and comes back to the cueball quickly, stopping any scratch.
I did make it scratch by shooting about 2 diamonds speed too hard!
That must allow the object ball to get out of the way enough!
I hope a better player will try the same test, and see if they come up with the same results /conclusion.
I will never give my opinion again, without actually trying it first!
I learned, what I think, is a very important concept, about frozen balls and speed, that I might never have thought of, otherwise.
