Which pair of digits in Winds Aloft notation indicates a variable wind with less than 5 knots?

In Winds Aloft, the main wind value is given as direction and speed, but if the wind isn’t constant, the forecast includes a small tail of digits to show how much it can vary. That two-digit tail is the last pair of digits, and it specifically conveys the variability in knots. When the variation is less than 5 knots, this tail shows a small value (below 05). So the last two digits are the part that indicates a variable wind with less than 5 knots.
