OS wind speeds

Hi Brian, i am a little puzzled with regards to wind speeds on the OS 968 station

I am noticing that the OS misses many gusts, i.e. you know that its very gusty between the update
yet none of the decent gusts have recorded, is this an OS thing? i was under the impression that
in between the updates the data is stored then grabbed on the next update of the data, is this not so?

I spose this is more of a station question but i thought perhaps WD grabbed the data?

Perhaps i was either misinformed or read it wrong?
