How accurate are you?

Duh,

Figured out what why my convergence score were way off.

Your inaccuracy by category:

Parallelogram 2.2 4.1 4.1
Midpoint 2.2 4.2 4.2
Bisect angle 0.8 1.9 6.0
Triangle center 6.4 5.2 2.8
Circle center 4.5 2.0 9.5
Right angle 3.1 5.5 4.2
Convergence 7.1 1.0 6.4

Average error: 4.16 (lower is better)
Time taken: 73.6
 
First time through it, I learned that I can't find the center of a triangle if my life depended on it lol, thankfully no triangles in pool.

Also, I can find a right angle and bisect an angle pretty well, but should work on finding the center of a circle. Maybe that's why I miss some shots? I line up the correct angle but hit the cueball in the wrong spot.

My girlfriend tried it and did better than me lol.

She did well overall but shoots as a D player, so I'm guessing stroke matters much more than seeing the shot.

Did it on a laptop with no mouse. Surprised the average scores havent been better on a pool forum. :p

I don't think so. We don't really know what the real world differences mean between someone who scores a 2 and someone who scores a 4.

Given what we know now about deflection it is safe to say that it's fairly easy to miss due to a bad stroke. And it's also fairly easy to get in the habit of using the stroke to compensate for poor aiming. People are very adept at overcoming obstacles. However it's really hard to maintain consistency if you are handicapped by either a poor stroke, poor aiming or both.

This is just a fun game to test people's ability to eyeball pinpoints and other people's assumptions about that ability. In reality no one truly plays with fixed contact points in my opinion. They play with approximate contact areas because a fixed contact point on a pool ball is next to impossible to "see" much less hold in your vision for any length of time. I think we all know people who see fuzzy balls and yet play lights out. At least I do.

I still think it's a pretty good training tool as well. Think about this, we talk about GB and finding the center of the GB, we talk about CTE and using the center of the cueball, and the edge of the OB but we don't talk much about how skilled any of us really are or aren't at actually finding those points.

Surely the ability to be able to properly "see" an angle or eyeball a spot or be able to mentally bisect a ball is one of the reasons that some people are able to line up better than others. But we never speak of training ourselves to get better at eyeballing these things. Sure we say you have to hit a million balls to figure it out, but do you really?

I wonder if putting time in on activities like this wouldn't cut down that million ball benchmark by quite a bit? I bet it would.
 
fascinating

For those that mis-click, you can point and click rather than drag and click. For me, it works better for some of the exercises but not for all.
Here's and idea that may open a can of worms: try doing this with only your dominant eye open.

The ones that especially apply to us as pool players are the exercises in being able to create a right angle and find the center of a circle.

I'm intrigued by this. Last night I generally did best on the right angle and circle. The parallelogram kicked my arse. Tonight, the pgram is my best, although I did get a 0.0 on a right angle. Crazy.
Thanks for sharing this.

Very good experiment---thanks. I will try this tomorrow to see if I improve.

id really love to see what scores would be like if there were no guidelines for the convergence of the three lines, the bisection of the angle, and the parallelograms. if all the parts of the game were just about the points in space i think it'd be more of a true test. the portions that use the guidelines are visually a little easier since you can also use the pixelation of the line as a guide to how well it matches up against the question's lines.
 
getting better. This is my second try.

k there s something seriously wrong with this game. i kept getting horrible scores on the right angles so i held a cd case against the screen about 5 different times on the right angle question and my point was exactly right every time but the computers was very clearly off sometimes by as much as 20% so even tho i did really well in the other categories including a 0.0 im wondering if any of them are accurate?
 
The parallelograms and triangle centers killed me.

It's your screen resolution. Look at the bottom of the page and click on the note about right angles.
 
3rd Try:

Parallelogram 2.2 3.6 3.0
Midpoint 1.4 6.3 2.2
Bisect angle 1.0 0.2 1.3
Triangle center 3.1 3.0 5.1
Circle center 2.8 9.2 2.0
Right angle 0.3 3.7 3.2
Convergence 5.0 2.2 3.0

3rd try: 3.04 194.4s
2nd try: 3.66 202 s
1st try: 5.97 206 s

So, it got better with each try.
Fun stuff.
