 ## Monitoring
 You will only monitor the **Latitude and Longitude, Altitude, and Distance** coordinates. But you can also monitor the **Accuracy, Time and Bearing**.
 
+## Distance Meter Calculation
+In order to show the meter to be accurated, I make some math calculation while assembling the code blocks.
+
+`speed * accuracy * 2`
+
+But it seems to have some problems, the issue #1 shows some consistencies whie testing. so this time before 6.48, I did this:
+
+`speed.format as decimal - places = 0 ` *
+`accuracy.format as decimal - places = 0` *
+`2`
+
 ## Tips to use
 - The speedometer on the app will be inaccurate in compared with the *actual car speedometer* in certain Android Devices. 
 - If you have a bicycle to use with the speedometer, Be sure to have a protective tripod to prevent you device from **falling** especially if you are riding in mountains, rough roads, or some dangerous places.
