GPSTC field 1 with Alpha 500

This Data field is designed to work along side GPSTC Datafield 2. It indicates your “2 Sec”, your “5 * 10 Sec” and your alpha 500 during a windsurfing session. Create a new Activity and add each datafield to a separate Data screen, configure each Data screen to have a 1 field layout. Put GPSTC Datafield 1 on Screen 1, GPSTC Datafield 2 on Screen 2, then configure Screens 3, 4, 5 etc to your personal needs. It displays: • The last 2 Sec run in kts. • The best 2 Sec run for the session in kts. • The average of your best 5 ten second runs in kts • 5 coloured bars showing the relative speed of your 10 second runs • Session distance in Km A second page displays • Your best Alpha 500 (Return to within 50 m of start point) • Your last Alpha 500 (Return to within 50 m of start point) • Your best Alpha 500 (Return to within 60 m of start point) • Your last Alpha 500 (Return to within 60 m of start point) • Your best Alpha 500 (Return to within 70 m of start point) • Your last Alpha 500 (Return to within 70 m of start point) “2 Sec Run” This field displays the best 2 second average speed from your last run. A run is considered to have been completed when you either stop or complete a gybe. “Best 2” This field show the best 2 second average speed for the session. The colour will change to red if this speed is above the user set target. “5*10” This field shows the average of your 5 best ten second runs. The colour will change to red if the average is above the user set target. The 5 coloured bars show the relative speed of the five best runs. The bar colour is green if within 5% of the best, orange if within 10% of the best or red otherwise. “Alpha 500” This page shows your best and current alphas. The alphas can be any length from 200 metres up to 500 metres. The watch only captures data for the last 60 seconds so the alpha must be completed within this time, this corresponds to a 16kt 500 metre alpha. Slower alphas may be recorded but they will be less than 500 metres in length. The two configurable alphas are preset at 60 and 70 metres. These can be user programmed to between 10 and 100 metres. Due to restrictions within Garmin watches only two user datafields can be assigned to an activity. So the watch alternates between the “2Sec + 10Sec” page and the “alpha” page automatically. The watch will display whichever page has the most recent new value, or if travelling at less than 5 kts it will swap between them every 5 seconds. The watch will play the “success” tune if either the 2 sec or 5*10 beat the previous best for this session. A user configurable Speed Genie (as used on GT31). The “2 Sec Run” speed will not reset until you have gybed and then your speed has risen above this number. On start up the Speed Genie that you have set will display in the "2Sec Field". The defualt is set at 12 kts. At the end of the session the following is written to the FIT file and can be viewed in the Stats panel of the activity in Garmin Connect. This function is not supported by the Fenix 3. • Best 2 Sec • Best 5*10 second • 5*10 speed 1 • 5*10 speed 2 • 5*10 speed 3 • 5*10 speed 4 • 5*10 speed 5 • Best alpha This data field should produce an accurate indication of the GPSTC categories. However this data is not approved for posting to GPSTC.
