I found discrepancies between wind numeric value and its representation
 
The wind vector shows 5 kt less than the numeric value when the speed is divisible by 5 kt.
If it is due to unit conversion and rounded value, e.g. 64 km/h = ~34.56 kt, rounded value = 35 kt, I suggest to round the vector to the closest value instead of rounding down, in the example vector of 35 kt instead of 30 kt.
Moreover, it is possible to show the wind vector for 5 kt with the short line at the second position like the third picture

You are right Tim. It's just that rounding down to the nearest 5 kts is arbitrary. You can make an argument for rounding to the nearest 5 kts. And you can find an argument for rounding upward to the nearest 5 kts. But rounding down to the nearest 5 kts is just arbitrary. Not that it would matter much. Simply hard to argue in favor of.
