<h2 style="color: #003594; margin-top: 0;">📊 How Ratings Work</h2>
|
||
|
||
<p><strong>One unified rating</strong> — Singles and doubles matches both contribute to a single ELO rating. Everyone starts at 1500.</p>
|
||
|
||
<p><strong>Per-point scoring</strong> — Your rating change depends on your actual point performance (points won ÷ total points), not just whether you won or lost. Winning 11-2 earns more than winning 11-9.</p>
|
||
|
||
<p><strong>Smart doubles scoring</strong> — In doubles, we calculate your "effective opponent" using:<br>
|
||
<code style="background: #e9e9e9; padding: 2px 6px; border-radius: 4px;">Effective Opponent = Opp1 + Opp2 - Teammate</code></p>
|
||
|
||
<p>This means:</p>
|
||
<ul style="margin-left: 20px;">
|
||
<li><strong>Strong teammate</strong> → lower effective opponent → less credit for winning</li>
|
||
<li><strong>Weak teammate</strong> → higher effective opponent → more credit for winning</li>
|
||
</ul>
|
||
|
||
<p><strong>The formula:</strong><br>
|
||
<code style="background: #e9e9e9; padding: 4px 8px; border-radius: 4px; display: inline-block; margin-top: 5px;">
|
||
Rating Change = 32 × (Actual Performance - Expected Performance)
|
||
</code></p>
|
||
|
||
<p style="color: #666; font-size: 13px; margin-bottom: 0;">Fair, transparent, and no mysterious "volatility" numbers. Just skill vs. expectations.</p>
