 #### Test parameters
-* __time_dl__: How long the download test should be in seconds. The test will continue regardless of this limit if the speed is still 0.00 when the limit is reached.
+* __time_dl_max__: Maximum duration of the download test in seconds. If auto duration is disabled, this is used as the duration of the test.
     * Default: `15`
     * Recommended: `>=5`
-* __time_ul__: How long the upload test should be in seconds. The test will continue regardless of this limit if the speed is still 0.00 when the limit is reached.
+* __time_ul_max__: Maximum duration of the upload test in seconds. If auto duration is disabled, this is used as the duration of the test.
     * Default: `15`
     * Recommended: `>=10`
+* __time_auto__: Automatically determine the duration of the download and upload tests, making them faster on faster connections, to avoid wasting data.
+    * Default: `true`
 * __count_ping__: How many pings to perform in the ping test
     * Default: `10`
