It looks= like that was just an average of the four ground speeds.  As winds al= oft get stronger, the error will grow.
With three or= thogonal ground tracks (not heading), one can get true airspeed and winds a= loft.  With four tracks you can cross check for errors.
VTAS =3D SQRT( V1^2 + V2^2 + V3^2 + V1^2 * V3^2 / V2^2 )= / 2
Wind Component in 1 direction=3D ( V1 - V3 ) / = 2
Wind Component in 2 direction=3D ( V2 - V1 * = V3 / V2 ) / 2
Total Wind =3D SQRT(W1^2 + W2^2)
