Instead, from another good source in Kourou at the time of the launch, it has been reported that LARES release was going to be considered good if within 20Km of altitude. It appears that the release happened within a few METERS of the target altitude.

But I do hope they keep this record.BTW, if the extra performance seen as a bug or as a feature? I.e. it's a pleasant surprise or a variance problem?
Dito. Thanks, dsky.And for anyone else who cares: Purely based on numbers shown during the webcast I estimated a 3rd stage orbit of -30 x 775 km (?) Also, the velocity peaked around T+1:40, 3:12 and 5:31 for each of the three solid stages. Thrust levels dropped sharply around these points in time and the vehicle - not surprisingly - appeared to be coasting towards the separation events while trading speed for altitude.
Big news!Here is a first movie of the VEGA launch as seen from the on-board cameras. Most of it is in a kind of slow frame rate, but at the end there is a high frame rate clip of the P80 separation.The whole movie has different events in it.I hope they will release a better one, but for now it is just great to view it!http://www.asitv.it/index.php?DLr=cN2xsU2L4yofyk3jfFrTWnhCxpaY9s
Good video to watch.
A little bit dicey on the last stage separation seen in the video, but everything worked. Note that the first stage of the flight does not appear to use roll control. - Ed Kyle

It seemed to be rolling almost as fast as the second stage of the first Falcon 9 at one point.The only information about roll control I've come across is that the AVUM provides roll control for the second and third stages (and for itself, of course.) So you could be right about the first stage.It seemed to keep on rolling even after first stage separation, but then sorted itself out. So AVUM appears to have done a good job and provided excellent control and accuracy.
Sorry to bump an old thread, but i'm looking for the total lift performance (in kg) for VV01 ? (press/launch kits only quote max. performance)Edit:and while we are at it, does VEGA have a launcher serial number ? like Ariane has for example VA214 / L 569
