 	<h2>Speed test for nano25519</h2>
-	<p>Times below are in milliseconds and are summarized by various averaging methods.</p>
+	<p>This test compares different Ed25519 implementations by running a sequence of functions. A random 32-byte value is generated for a message and private key, and then the test uses the values to derive a public key, sign the message, and verify the signature.</p>
+	<ul>
+		<li>Each derive-sign-verify sequence is timed as a unit.</li>
+		<li>Each test is comprised of the specified iterations of sequence units.</li>
+		<li>Each test run is comprised of the specified iterations of tests.</li>
+	</ul>
+	<p>The final score is displayed as "sequences-per-second" and is calculated as follows:</p>
+	<ol>
+		<li>For each test run:
+			<ol>
+				<li>Collect all the derive-sign-verify sequence timings for the test run.</li>
+				<li>Truncate the results by eliminating the fastest 10% and slowest 10% of sequence timings.</li>
+				<li>Calculate the arithmetic mean (average) of the truncated results.</li>
+			</ol>
+		</li>
+		<li>Collect the truncated arithmetic means from all test runs.</li>
+		<li>Truncate the results by eliminating the fastest 10% and slowest 10% of test runs.</li>
+		<li>Calculate the harmonic mean of the truncated results.</li>
