Let me try to explain my position more clearly and lets forget about the 5 shots for now. Imagine that you have a single shot, that calls for a CTE/ETA visual with a left sweep to be pocketed.
1. I can only see the CTE/ETA from one head position which is the fixed cueball that Stan mentions in his videos. This is the most important point, from which my argument flows.
2. No matter where I approach the shot from my head will always end up in this position, so long as the CTE/ETA lines line up correctly.
3. Now lets imagine that I shift both the balls two balls widths to the left, but that the shot still calls for the same visuals and sweep.
4. My position then is as follows: As far as the cueball/object ball/head relationship is concerned, nothing has changed! Relative to the cueball and object ball my head position at "fixed cueball" will be exactly the same as previously!. Yet, to hit center pocket, the cue ball must contact the object ball at a different location.
I don't care about being "right" about this issue, but I hope this clarifies my position on the matter. If I'm wrong about this, then I'm happy to change my mind, as I'm not one to get married to any position. Nor am I interested in insulting people, at least on purpose.
