Yeah, Lil Chris is more straightforward with his version, and he doesn't use a lot of unnecessary words about aiming with spheres on a two by one surface.
The main difference between the two versions is this:
With Chris's version the ob itself is used to determine the final aim line, meaning you are lining up to a reference point on the ob then pivoting to ccb. But there is only one pivot direction, an "inside" pivot as Stan would say. This is very much like the shishkabob system that a friend of mine uses.
With CTE Pro1 you do not pivot/sweep directly from any reference point on the ob. You pivot from left or right of the fixed ccb line you get from the 2-visual perception method. The results, when shooting the same given shot using each method (Chris's and Stan's), will not be the same. Of course, some shots will happen to work with both methods whenever Stan's "perception" line happens to be lined up to the same ob reference point being used with Chris's method.
But think of this..... If I ask you to aim straight through ccb to "A" on the ob, and shoot from there, it will create about a 15° cut angle (fractional aiming). Now if I ask you to aim straight to "A" from a half tip right or left of ccb, then pivot to ccb and shoot from there, it will create a thinner cut angle, thinner than 15°. Depending on bridge length, which is lil Chris's pivot point, and the distance between cb and ob, the created shot angle could be anywhere from about 18° (when the ob is close to the cb) to 90° (when the ob is very far away from the cb). The pivot is always thinning the shot when you pivot from inside the cut angle as Chris shows. With fractional aiming you simply aim thinner or thicker than "A" if the shot looks a little thinner or thicker than 15°. You control how much thinner or thicker by controlling how far from "A" you aim. With lil Chris's pivot method you have only one option, one cb reference and one pivot angle that thins it up.
With Stan's CTE 2-line visual perception method, you use inside and outside pivots, which at least gives you some variance on manipulating the shot angle to make it a little thinner or a little thicker, which is determined by the fixed ccb perception you get between the cb and ob after getting your visuals. Again, from this fixed cb "perception" you decide if it the shot looks thick or thin, and then you use an inside or outside pivot to thin or thicken the shot up. With lil Chris's method this is not an option. He only shows inside pivots, which always thins the shot.
