Volume analysis by ghostly hand, or is it just me?

MM seems to do weird volume analysis stuff, it seems improbable but I have no other explanation at the moment. This happened several times but not always, so it's hard to reproduce.
The option "automatic volume analysis" is turned off, as always, I start the analysis manually when I want to. Per album analysis and leveling options are checked. "Update id3 tags when changing properties" is checked.
I add a couple of new albums (folders containing mp3s) to the library that contain no volume leveling information. But at some point later I notice that e.g. two of the albums show a track volume leveling entry in the respective colums of the library and playback windows. When I open the "properties" dialogue for one of those files, the field says "No". When I open Mp3tag and look at all tag fields, there are no corresponding tags! For one specific example, only one single mp3 file contained the tag "REPLAYGAIN_TRACK_GAIN": the only one file I previously played in MM and that I rated (i.e. that triggered the tag update). But that track also shows a "No" in the MM properties, like all other. This also proves, that the leveling information did not come from outside MM before importing the file into MM.
When I manually start volume analysis, everything is fine.
BTW, the track volume level information is not always accurate: when I manually start the analysis, much leveling info is correct, but quite a few are off just some 0.1 steps (1/10 db). This is even more weird.
This happened to music both from friends as well as my own CDs ripped with EAC (having volume leveling turned off in EAC). I checked all files' tag info using mp3tag before adding them to MM. Is there maybe some hidden info, or is MM malfunctioning?!
