David,
 The RUC fits raob winds within 2-3 m/s RMS vector
difference (analysis minus ob) at 850-700 mb, and
within 3-4 m/s at 300-150 mb. We do not have info
on speed fit to obs, but by definition, it is
somewhat less than the vector fit, so probably
1-2 m/s.
ACARS aircraft data fit is also about 2-3.5 m/s
RMS vector difference.
Is this the kind of info that you wanted?

Stan
