Two-minute averages are rounded to the nearest knot and nearest degree.

minute 1 | 3 | 4 | 2 | 5 | 7 | 6 | 4 | 2 | 4 | 6 | 5 | 5 |

minute 2 | 6 | 3 | 4 | 7 | 4 | 5 | 3 | 5 | 2 | 5 | 6 | 4 |

The 7 missing 5-second average wind values would result in a 'missing' 2-minute average wind speed and direction.

If more than six 5-second averages are missing during the two minute calculation period, the 2-minute average wind values are marked missing.

minute 1 | 3 | M | 2 | 5 | M | 6 | 4 | 2 | 4 | 6 | M | M |

minute 2 | 6 | 3 | 4 | M | 4 | M | 3 | 5 | M | 5 | 6 | 4 |

The sum of 107 gives a 2-minute average wind speed of 4.45, or 4 knots, rounded to the nearest knot.
