Yes!  We have developed a 5 point calibration routine that saves loads of time without sacrificing precision.  You can read about it here: https://kinarm.com/technical-bulletin-kinarm-gaze-tracker-impact-of-reducing-the-number-calibration-targets/ .
Note the post includes instructions on how to implement the change in Dex 3.9.1 and later.  (This method will be our new ‘standard’ with the release of Dex 3.10. planned for early 2023.)
