Frequently Asked Questions
How is the score calculated?
We use a sophisticated algorithm. First, we find the geometric center of all points in your drawing. Then we calculate the distance (radius) from the center to each point. The score is based on the standard deviation of these radii. A lower deviation means a more consistent radius, resulting in a higher "perfection" score.
Is the global ranking real?
The global ranking is a realistic simulation designed to be motivational. It's based on a statistical model where higher scores are exponentially rarer. While not a live leaderboard, it gives you a great idea of how your skill compares on a global scale!
