Milking Prep Lag Timer

The app uses a push button interface to track the timing of the various stages of the milking procedure, with the flexibility to choose the stages and number of cows to time. The user specifies which pen and how many cows are in the preparation sequence. In additon, a turn timer is provided in the upper right hand corner of the view.
When the app is initiated, you may identify the herd and scorer name in the appropriate text fields. Next, you must setup the routine. First enter the pen number by touching inside the Pen textbox, touch/type the desired identification then touch Done.
Next enter the Number of Cows in the Preparation Sequence – for spatial prep sequences, this is the number of cows a milker prepares before starting the prep sequence again on another group of cows.
Enter the Number of Cows Timed by touching the textbox. A selector will open, touch the desired number (1-8) and touch Done. Novice evaluators will want to start with 2 or 3 cows, while more experienced operators may choose up to 8 cows. Note, number of cows timed does not have to equal number of cows in the prep sequence. You may sample any cow or cows in the prep sequence; eg. the first cow, the middle cow, the end cow, etc.
Next, the user will select the milking preparation steps. Touch inside the Step 1 textbox and select the preparation step using the selector. Touch Done to finalize selection. Repeat until all steps have been assigned. The setup up process is structural and must occur in this order. After all steps have been assigned and you are ready to begin timing, touch the Activate timing buttons button. The first row of timing buttons will become enabled with a white border and the other buttons will have a gray border until they become activated. When the procedure is initiated for each parlor position (cow), touch the button. Times will be recorded and the button for the next step will be enabled with a white border showing. If a button is touched inadvertently, press it again to negate or undo. The recently activated button will become inactive and the pressed button will return to a white border until repressed. When the whole sequence of cows is completed, all timing buttons will have a blue border. To score another sequence of cows, touch the Reset to Score again button. This action will automatically advance the Round to 2. If a new Pen is scored, the new pen numb
