Absolutely not. You should move it at least in a half-meter range for good calibration results. Also make it tilt and yaw slightly, holding its sides parallel to the floor. And ensure its corners are not in touch with your body - hold by the middle of a side, not a corner, in a straight arm.

More motion is better--holding the board absolutely still does not give the tracker enough useful information to reconstruct the camera positions. And especially include back to front motions--this tells the tracker which camera configuration you're using. Move the board smoothly though--jerky motions may cause issues because Kinect is only 30fps and the recorded data is not necessary in sync to the exact frame all the time.
FYI, I typically record about 400 to 500 frames for calibration. Shorter sample (200 frames) is okay but more frames improves accuracy. That said, any more than 500 is probably overkill and unnecessary.

Thanks! well, last sunday we recorded
a lot of video... ashame, but it's only a fraction of the whole for a project, really appreciate the help! in the next sessions we'll do it right!
