<h2>dartboat</h2>
<p>dartboat uses an internal representation of a specification dartboard. Darts are thrown following a normal distribution, with the resultant coordinates used to calculate the segments in which they land. The idea is that this provides a more realistic opponent than picking points at random.</p>
<h2>Settings</h2>
- <p><span class="icon">&#xf597;</span> <em>(delay)</em> — milliseconds it takes the computer to throw each dart.</p>
- <p><span class="icon">&#xf1de;</span> <em>(stdev)</em> — the standard deviation of the computer's throws in millimetres. A value of 24 translates to a three-dart average of roughly 35. A value of 13 would be a 65 average, and a value of 8 a 95 average.</p>
+ <p><span class="icon">&#xf597;</span> <em>(delay: 0-9999)</em> — milliseconds it takes the computer to throw each dart.</p>
+ <p><span class="icon">&#xf1de;</span> <em>(difficulty: 0-99)</em> — precision of the computer's throws. Starting with a three-dart average of 10 points at difficulty 0, every difficulty increase of 8 corresponds to an average points increase of 10, e.g. difficulty 32 would be a 50-point average. (The rate of increase quickly increases upon reaching an average of 120 points.)</em></p>
<h2>Interface</h2>
<p>To avoid destructive actions being a misclick away, certain actions require two presses—one to activate the button and another to trigger it.</p>
<p>The controls are designed to be keyboard-friendly. The keys should be fairly intuitive for the most part.</p>
