I had the same problem with the gloves when sitting. It seemed to fix itself when I stood up. I managed to get two knockouts.

It appears that we are diametrically opposed in our playstances, as my only major concerns with your game was about defaulting to a seated position as a standing player! Yes, the calibrator is designed to work after the headset reaches a certain height, which is what you discovered upon standing. Thank you for playing!
