Good Morning,

How does SeeYou calc wind speed and direction when you are reviewewing
flight logs.

I notice the wind shifts direction and velocity ... even while running
ridges ... so I assume it is not using some measurement of drift while
thermal-ing ...

It depends on the IGC file, there may be TAS data in the file or wind
vectors in the K-record in the IGC file. This has been discussed here
in the past. For a plain IGC file SeeYou can only use circle drift.
