Elevator Speedtracking
When you track the speed of an elevator using the BENO Elevator Speed® app on your Rinky Dinky Android. It is done by holding the phone up against the wall with the app zoomed in on the SPEED (preferably in meters per second) and DISTANCE. Stand near the panel so u can push buttons quickly upon arriving at your floor. When you feel a push, numbers will go up, when you feel deceleration numbers will go down.
