Wind: reading direction

Wind Indicator The in-game wind display can be activated with the default key bind: Shift + K. The indicator will appear in the top left of the screen and display information for both wind direction and wind speed. In a similar fashion to a soldier experiencing wind without any devices to precisely measure velocity and bearing - this indicator does not provide precise values or directions, only estimations. With an understanding of the systems and methods in use to display these estimates, information precise enough for marksmanship may be gathered for use. Direction Values The wind indicator displays wind direction with an arrow, pointing towards the blow of the wind. The direction of the arrow, however, does not track very precisely - only updating the indicator once every 30°. Although a 30° margin of error is relevant considering how severely a moderate wind can deflect a bullet, the 30° direction brackets create 12 even display directions, making range card use with the wind indicator a simple task alongside the clock method. Looking towards a more precise answer for long range marksmanship, we can find the exact values for wind direction by understanding the angle values at which the wind direction indicator changes. These values at which the arrow changes directions can be used to determine an exact wind bearing, for use with calculations. Precise values attached to the wind indicator are diagramed below:
