CWOP 10 minute average

Build 16, ver 10.37i, mentions “Fixes 10 minute average windspeed option for CWOP data.”. What’s this about? I haven’t found an option for this in the various setup screens, other than to have WD display this from my Peet 2100 unit. How does this affect CWOP data?

sorry for the confusion
its for when using the Wxnow.txt update or aprs out a com port option (see under setup)
