Bambu, there are 2 visual lines in ctepro1. Each line has a specific function.
The cb edge to ob aim point is an AIM LINE. Your task is to aim a cb edge to an ob aim point.
The CTE line is a SIGHT LINE not an AIM LINE.
The cteperception allows the shooter to know the cb edge to an ob aimpoint is correct in establishing a fixed cb.
Let' s you have 6 diamond cb ob separation and a cut to the left. Your ob aimpoint options are A B or 1/8 ball overlap.
Rule out B simply because distance will not permit cb edge to OB B with a center to edge perception.
So, left cb edge to OB A and check your cte perception. Now you have 2 visuals required for any cte shot.
The shot may be on.
The other option is a single line for a1/8 overlap. Any 1/8 ball overlap may require either a left or right pivot. No CTE for this shot.
All shots that have 2 line visuals must be seen with zero head movement and only eye shifts.
**Important:,an OB aimpoint AIM LINE positions the eyes for the proper cte offset. Your nose is NEVER behind a cte line as if you are aiming.
TOO much emphasis is placed on getting directly behind the cte line. Not good!!
Hope this helps.
Thank you Stan, is the object ball aim point the actual contact point, or the edge of the object ball?
