You guys who find the WP thermal assistant so much better than others - are you running them on the same hardware with the same inputs? I hope you are not basing any comments on an Oudie using its internal GPS because it is known that the info from the internal GPS is not good enough for a thermal assistant.

You are absolutely correct. WP Pro is only available and only work with a compatible flight computer( true airspeed and vario info added I think) and not with a stand alone gps source.
SYM, XCSoar will offer their version of the thermal assist with a stand alone gps where they should not; AS IT DOES NOT WORK without a flight computer!
But to be honest when it comes to their type of thermal assist SYM and XCSoar don't work very well with a flight computer either.
I'm sure this is all about the algorithms which they won't openly share (as in guarded secrets).
Like Tim I have used all three (and still have them installed on my Avier/Vertica2)
None measure up to WPPro when it comes to this feature. Agree; they have a lot of new and nice features I wish WP would take notes of.
(One would argue; why we need the thermal assits? Answer; why do we need flight computers, compensated varios, audio varios, or a variometer for that matter??.)
