8bitdo pro 2 hall joysticks calibration issue

8bitdo pro 2 gamepad with hall effect joysticks has an issue that after pressing the left stick it extends (recalibrates) it's value range beyond the range in the unpressed state, so (in my case) ultimate UP (forward) direction does not register as 100%, so e.g. running mode in games becomes unreachable with the extreme stick position (until you push it). There's an undocumented firmware recalibration mode: https://www.reddit.com/r/8bitdo/comments/1dtkoqx/sticks_are_not_aligned_anyway_to_calibrate_this/

  From 8bitdo support about the Pro 2: 
  
  L1+R1+SELECT Hold 10sec start calibration
  
  Rotate both joysticks 3turns *Simultaneously clockwise
  
  Fully press both triggers 3times Press all combination keys again to complete the calibration
  
  Turn-off the controller then turn on again
