I think there must be something missing from this description. By "line up" do you mean "sight" rather than "aim?" Are you making any conscious offset of the stick from the sighted CTEL? How are you choosing your body placement? How are you choosing a point from which to pivot the stick?
I was giving the super condensed version - just like the DAM system.
Sorry, I just get really tired of every time we are having these discussions on CTE - here comes Dave to tell us that the only way to aim is to use ALL available methods and go with the best guess.
It gets a little tedious to see him linking to this DAM method which he only created to MOCK people like Hal Houle.
In the other thread we are discussing CTEL and people are starting to contribute videos - I predict that we will come to a better understanding of the exact procedure.
Will we ever have a set of instructions that includes exact measurements?
Well I think it's certainly possible although they wouldn't do much good in a game since you aren't allowed to use any thing to mark the table.
Dave Segal has drawn up some diagrams which show foot placement and body alignment on "thick cut" as well as "thin cut" pivots. I'd suggest that people who want and need such information to start there.
My answer to Dave Alciatore could have also been like this - I visualize a ball sitting in line to the pocket and get down and shoot my cue ball straight into that ball. That's the GB method at it's simplest description.
