As an aside . . . there are two versions of WinPilot, WinPilot
'Advanced' (all purpose) and WinPilot 'Pro' that **requires** one
of the following devices to be connected to get accurate info:

a.. Cambridge 302 vario/flight recorder
b.. LX1600, LX 5000, LX7000, LX 160
c.. Westerboer VW921/922
d.. or a Borgelt B50 (with a gps-unit)
(from http://www.winpilot.com/gps.asp)

The **Pro** version is apparently able to derive wind info in
straight flight as well as the 'Advanced' version's derivision
from thermalling ability.

I tend to agree with Marcel. I also fly with an ILEC SN-10 and
an IPAQ
with Winpilot. My sense is that algorith and precision from the
SN-10
is always more accurate than Winpilot. The reason I say this is
the
same as what Marcel mentioned, which is the ILEC is capable of
calculating windspeed and direction while in level flight,
whereas most
other software/computers require you to be circling.

Doug,

I'm curious to know how much variation you get between the two,
if any.

I use WinPilot Pro 6.x and an LX7000 Pro, and the two wind
indications
are usually very close.
