Thus methods that don't use a pivot, i.e. parallel english, don't have a pivot point. They do however have a point at which cue offset cancels deflection, but don't use it in favor of controlling curve and throw to cancel deflection instead.
I would tend to agree, but...
'Well, that depends on what the definition of is, is.' (Bill Clinton)
To what are 'we' relating 'parallel'?
I have been using what I would call 'parallel' english for nearly 46 years.
1. You line up a shot,
with your eyes, from the center of the cue ball to the center of the ghost ball location.
2. You decide what amount of tip offset you are going to use.
3. You mentally adjust the ghost ball position accordingly.
4. You come down on the shot with the cue stick 'parallel' to the visual centerline running from the center of the cue ball to the center of the adjusted ghost ball location.
5 You shoot the shot with the cue stick running 'parallell' to the 'visual' line of the cue ball center to the center of the adjusted ghost ball. Hence it is 'parallel' to the
visual center line.
Does the cue ball travel in a 'parallel' straight line, parallel to anything? No.
Is it a 'parallel' sight or aiming line system for aplling english? I'd say so.
Is it different from BHE, FHE, & a combination of the 'normal' BH/FH English, where they go in opposite directions? I'd say so.
So, it depends on what the definition of
is 'parallel',
is.
I also will get down on a shot first and then shift the whole cue, front & back including my bridge hand,
to the side for a
newly desired tip offset, 'parallel' to the sight line, or I will use BHE, FHE, or a combination of both.
Do these things require the correct foward speed to spin ratio? Yes. Are they a bit 'complicated'? A bit. Are they TOO complcated to be useful? I certainly do not think so.
