Useful - yes, but way down the list of sources I use. with over 250 hours and 20,000km x/c flying in the last 12 months, I've found XC Skies so reliable I've almost stopped looking at anything else. Most comps now don't seem to bother with flying a temp trace at all as the results have usually not been as reliable as the predictions !
The problem with measured soundings is that the information has a good chance of not being relevant, either due to distance or time resulting in the flight being in a different air mass.
