The best evidence suggests that when exporting a file, The export dialogue parameters are misleading. If once Alex -16 LUFS and mono, the best evidence suggests that it is auto adjusted to be -19 LUFS, which is the mono equivalent to -16 stereo. But there’s no indication in the dialog box that this is happening. Therefore, if an informed user, recognizing that -19 LUFS is the correct setting for mono, manually changes the output setting to -19 LUFS mono, they would — if the protocol continues — get a resultant file of -22 LUFS. This automatic adjustment and conversion is not explain to the documentation anywhere that I have found, and nor is there any sort of an alert or clarification of this process in the dialog box during the export process. This will lead to in accurate files as a result.
