I think many computers (or software) counts for wind variations due altitude.

You think? For example?

For flying in convective conditions this is just plain wrong and misleading.

Actually, it can and often does change significantly
(out in USA west for example). But, the more important
input to final glide is completely differing wind on
final glide from the point the glide is planned (think
final glides to Minden or Gawler, or any mountain site).

Hope that helps,
