 // The first line of the experiment is the internal name. If you'd like to
 // gather statistics about the usage of your flag, you should append a marker
 // comment to the end of the feature name, like so:
 //   "my-special-feature",  // FLAGS:RECORD_UMA
 //
 // After doing that, run //chrome/tools/extract_actions.py (see instructions at
 // the top of that file for details) to update the chromeactions.txt file, which
 // will enable UMA to record your feature flag.
 //
-// After your feature has shipped under a flag, you can locate the metrics
-// under the action name AboutFlags_internal-action-name. Actions are recorded
-// once per startup, so you should divide this number by AboutFlags_StartupTick
-// to get a sense of usage. Note that this will not be the same as number of
-// users with a given feature enabled because users can quit and relaunch
-// the application multiple times over a given time interval.
-// TODO(rsesek): See if there's a way to count per-user, rather than
-// per-startup.

+// shows you how many (metrics reporting) users have enabled the flag over the
+// last seven days. However, note that this is not the same as the number of
+// users who have the flag enabled, since enabling the flag happens once,
+// whereas running with the flag enabled happens until the user flips the flag
+// again.
 
 // To add a new experiment add to the end of kExperiments. There are two
 // distinct types of experiments:
 // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE
 //   macro for this type supplying the command line to the macro.
 // . MULTI_VALUE: a list of choices, the first of which should correspond to a
 //   deactivated state for this lab (i.e. no command line option).  To specify
 //   this type of experiment use the macro MULTI_VALUE_TYPE supplying it the
 //   array of choices.
 // See the documentation of Experiment for details on the fields.
