1. Wow! some hurting people here have clearly been burned by "aim systems". I understand and that's why I came to the thread reluctantly after seeing my article cited out of context.
2. About.com as a company seeks fans to write about fandom, if you want to think of it that way. They know that hiring a fan of fast food will produce better writing (and more writing) than someone who is hired to write in a subject they don't care for. About is for "beginners and up" and I'm one of the rare writers there who offers instruction in the subject as much as observation.
There are highly intelligent readers and writers at AZ and I was not looking to slur anyone.
3. The adjustments I mentioned to both G.B. and C.P. aim have to do with # 3 below and with Kranicki's views not on parallax aiming but on false ball equators send while erect and yes, adjustments should be made in their air, certainly, of course.
However, the average players who lines up contact point and then with their eyes and mind decides to hit still thicker than that while in the full stance still is likely pointed more thinly and will stroke there also.
4. I can restate it this way also. There will be some "rail drivers" who take my advice but they are VERY rare exceptions. The average player does not aim and/or stroke to where they think they've aimed. If they did, they'd sink more balls more often, right? Everyone would play at an A-B level or more.
Most players stroke more thinly than they aim on the object ball. Most amateur ghost ball players constantly and severly overcut shots as one consequence; contact point players tend to stroke more thinly than contact point and score more often.
Again, if you hit a ball more thick, yet use a soft or soft-medium stroke, you generate more throw than the "bangers" do.
I've shown many fine players to hit challenging cut shots more thick and they say, "It won't pocket that way." And I say, "Humor me, and hit a few thick yet with that soft stroke we've been working on." And they pocket shots that are "tough" for them several times in a row and soon realize they have gone to a whole new pool game.
5. Part of the "pros spin balls" in that is mentioned in this thread is due to the fact that the pros take softer strokes than a lot of people realize:
My Recent Article - 10 Reasons Why Pros Shoot Most Balls Softly
Many readers have been to a pro tournament in person where the sound of cue tip to cue ball is barely heard. TV employes close up microphones where contact sound is exaggerated and enhanced.
Another aspect of "pros spin balls so they go geometric" has to do with them using, tiny, fractional amounts of english. Very little indeed. But know that most "say" they line up on the contact point.
6. My "geometers" comment was not intended to patronize or insult any readers but rather to forestall yet more comments about how "contact point is too thick" and "ghost ball is geometrically accurate". I know both those facts already as probably 98% of AZ readers know it.
But then ask yourself why so many top players say they aim contact point instead (and then edge-to-edge/eclipsing/sliding like others have said on this thread for thin hits)?
They are being honest about their aim methods and desire to contact the object ball more thick than a ghost ball hit.
