+ - Power distribution histogram: Rob Carlsen said:
+        
+        I believe that it displays the percentage of time that you've spent in
+        various power ranges, however you can change that to display the
+        absolute time you've spent in each range. the default is 20 watt
+        increments, but the recommendation in the book is to decrease the
+        granularity to 10 watt increments for better estimation of your FTP.
+
+        i thought that using this chart to estimate FTP would only be useful
+        when there were MANY workout files compiled, rather than looking at
+        one workout. all the charts on the "athlete home page" of WKO+ seem to
+        display a collection of past workouts, usually about the last 28 days.
