Something about pool that you could read on a rainy day.

Caution:- What you read on the pool dogma page is IMO

Recognize a 1/2 ball 30 degree cut, and the 1/8 ball angles.
Paralysis by aiming analysis happens by thinking too much.

IMO you should readily recognize a 30 degree angle... Question #19 on the above link.

Many players use visual overlaps & have for years.
IMO the ball overlaps can be more precisely found.

No math involved.. Just knowing your aim point for
Center CB.. You'll only need to know the pocketing
angle that the OB will go if the CB hits at that point.

If center CB is aimed at center OB ( line 1) it goes straight.
If center CB is aimed at the OB edge (line 5) ....it goes 30*
If center CB aims 1/2 way between 1&5 (line 3) it goes 15*
Whatever OB line is aimed at, it can be seen & will repeat.

The cut angles do not increase linearly as the overlap decreases, but your approximation of 7.5 per eighth of overlap works fine out to the half-ball aim.

Here are the cut angles to a little more precision for each eighth of overlap or fullness. It's important to note that these cut angles ignore throw.

Overlap (Fullness) -- Cut Angle
  • 1 (straight on) -- 0
    7/8 -- 7.2
    3/4 -- 14.5
    5/8 -- 22.0
    1/2 -- 30
    3/8 -- 38.7
    1/4 -- 48.6
    1/8 -- 61
    0 -- 90

Using 'IMO' as often as you do shows insecurity.

We already know it is your opinion. You wrote it, so it is obviously your opinion.

When someone prefaces or ends a thought with IMO, I dismiss 90% of he says. He only writes that because he can't back up his statement and is deathly afraid of someone arguing with him.

It's also a form of courtesy, implying that other opinions are welcome.

It's also a form of insecurity when a person greatly exaggerates something in order to prove their point.

I have seen this referenced before, I wonder why you want to scratch off the black?

The black spot on a 6x12 was the red-ball spot at English billiards...that game predates
snooker.......a red and two cue balls at that ......there were three ways of scoring....
...make a carom, make the red, or go in-off either ball..( called a losing hazard)....
....so that half ball angle was important for the cue ball also.

What I meant by linear was the horizontal line bisected by the 5 vertical aim lines.
I didn't mean the cut angles increase linearly. If vertical lines follow the contour of
the ball they wouldn't be equally spaced.. (like longitudinal lines on a world globe)
and would be increasing narrower from center to edge. Think of a flat disk instead
of a sphere, with evenly spaced lines, or 5 vertical aim points on a pencil glued to
the front of the OB. CCB aim at the 5 points would be OB overlaps center to edge.

I know 1/4 ball isn't exactly 15*.. If someone put both arms up, one at 15* and the
other at 14.5*, I doubt if I could tell... 0, 15 & 30 are just easy to remember. IMO

Thanks for 1/8 ball overlap angles increasing wider than 8 degrees after 30*.. Carl

Yes, I understood what you meant. My comment about non-linearity was referring to your use of the equally spaced angles of 7.5, 15, 22.5, and 30, not to the spacing of the vertical aim lines. I know you just use the multiples of 7.5 as "close enough" out to the half-ball aim; I agree. For anyone interested, I just listed the cut angles with a little more precision.

I hope you don't work at the US Patent office. Patents or copyrights mostly belong to IMO folks.
If you dismissed 90% of what I'd written, I hope you find something of interest in the other 10%. IMO
