This i a port of my original DIY datafield: https://apps.garmin.com/de-DE/apps/b0346b71-bf01-4070-96d6-3de66dcc8233

Please read the important notes below!

To create a layout, download the windows executable here: http://public.stattegg.info/WFL_HM_DIYD_2.3.0.zip
(examples for multiple devices are included)

It has special values for the WINGS FOR LIFE WORLD RUN

* Ahead time for a given target distance/time
* Predicted target distance/time
* Distance to catcher car
* Distance correction. By pressing the lap button distance is rounded to the nearest kilometer (4.8 to 5.0km; 6.1 to 6.0km). 
   When correction is active it is indicated by the "WFL offset indicator" (little yellow circle (not available on low memory devices))
   When lap button is pressed within 30 seconds again, the offset is reset.

The values are calculated by elapsed distance/time and average pace over the last XX (adjustable) seconds (300 for 5mins).
Ahead time and predicted distance are written into the fit file (except low memory devices).

You can create your own layout by creating a configuration string.

----------------IMPORTANT--------------------
Low memory devices (FR235, FR630, F3, 920XT, ...) can only add these values and the limit is about 15 elements and no dynamic colors are available!
* WFL Average pace
* WFL ahead time
* WFL pred distance
* WFL pred time
* WFL distance to Catcher Car
* Clock time
* Timer time
* Elapsed Distance
* Current pace
* Average pace

All other devices have all above and these additional values available:
* Maximum pace
* Total ascent
* Total descent
* Curr. heartrate
* Curr. heartrate %HFmax
* Average heartrate
* Maximum heartrate

One element with a value type "WFL Average pace" has to exists (it doesnt need to be visible, it can be in the background), because the calculations base on this value. 
The field in  element "WFL Average pace" -- "Nr of values" in the designer represents average over seconds, default is 5min (300s).

One more important thing is when pressing lap button for setting the exact distance at a kilometer marker: You have the option to clear the offset if you press the lap button again within 30s. BUT you will have to press the lap button again at the next kilometer marker if you have autolap enabled!! The reason for that: Because I cannot differentiate between a lap button press and an autolap event, you would get an autolap event 1km after you have reset the distance and then the offset would be set again.
-------------------------------------------------------

Because of memory limitations and the complex calculations for the prediction I had to remove some available values from the original version.
