+### [App Metrics](https://www.rowinginmotion.com/app/metrics)
+
+#### Stoke Effiency
+
+The area under the speed graph.
+
+#### Catch Duration
+
+The time the boat is decelerating at the catch (sec)
+
+#### Catch Efficiency
+
+The slope between the point of maximum negative acceleration and the point
+where zero acceleration was first hit.
+
+#### Check Factor
+
+The difference between maximum and minimum boat velocity.
