A few weeks ago, out of curiosity I made a few flights (P15&F15) with my Arixtra+, carrying a Graupner GPS/variometer telemetry module. I'm not so sure of the accuracy of the logged airspeed, especially when climbing and descending (not sure how 'clever' calculations beeing done). Anyhow, here is a plot from one of the flights (seems to be F15) showing the altitude [m] (green) and speed [km/h] (blue) :
