Software 20.00 Altimeter Continuous Auto Calibration

New functionality added to Enduro software ver 20.00:
'Update the altimeter’s auto calibration to be either be “On” or “Nightly”. Setting to “On” will calibrate at night, activity start, and continuously during activities. Setting to “Nightly” will set the device to only calibrate altitude at night.'
 
What would it mean for the the Enduro when it finally gets continuous Auto Cal.? I've read from multiple sites that people have found issues with contnuous Altimeter calibration on their Fenix 6. Does having the altimeter continuously calibration during activity affect the outcome of total elevation gain? I understand that's more to do with the performance of the Barometer more than the Altimeter ... or perhaps now both?
