Due to the calculation method used and the small accuracy that minecraft provides, the accuracy is limited. To improve the accuracy of
your result, throw from positions that are further apart from each other. See the video for tips.
The calculation may be off by a lot!
The calculation is probably off by only a few hundred blocks.

Get 2 Eyes of Ender
Press F3 to open the debug screen
Make sure you have a clear vision of everywhere the eye could fly towards, then throw the eye.
Align your crosshair to the exact position of the eye, then enter your position and rotation into the website below. Make sure to add the rotation as the exact value.
Move to a different location. It should be at least 100 blocks away from the first, 200 or more would be better. Don't move directly into the direction of the eye,
instead try to move in a ~45° angle to it for the best results.
Repeat step 2-4, entering the values into the second throw fields.
