WDisplay has the following tags:

Beaufort wind force number
Current Beaufort wind speed
10 minute average speed, in bft number
Beaufort scale in text (ie Fresh Breeze)
Beaufort scale in text (ie Fresh Breeze) based on 10 minute average

These are WD's own descriptions of their tags. Not clear to me if these
are gusts where they are not stated to be average. But presumably ...

I can't work out what those tags mean. How can you apply the Beaufort
scale to something that isn't based on an average?

When I had a look at it - some time ago, admittedly - there was an
option to make the wind display gauge on the main screen show the wind
speed as a Beaufort number. If you turned it on, the number displayed
varied with each reading from the station i.e. it appeared to be
applying it to the latest 'gust'. I reported this in the support forum,
but I don't think I was able to make myself understood.

I think that's the triumph of 'the customer is always right' over
technical accuracy. In other words, if one of the main drivers of your
software development is to add features without due regard for their
accuracy either that a user requests as a good idea or that they may
have seen - possibly inaccurately implemented - in another package
then that's the consequence. Another similar symptom is the provision
of a (calculated) cloudbase height based purely on surface temperature
and RH. It may look pretty as an iconic presentation - and of course
that's what sells it - but is likely to be wrong more often than it's
right.

I have to admit I added that to a recent version of my software, but I
wasn't completely comfortable with it. And it only appears (optionally)
on web pages, not on the PC display or anywhere in the recorded data.
