Well, lets see.
The timescales can be different.
Not all the media is used in the track.
The media may be used multiple times in the track.
The track has blank spots where there is no media.

there may be other reasons.

How does the Media Handler's duration value correlate to the Track Header's duration value ? Is it related in some way ?
Track Header [tkhd]
    duration= 18579
Edits [edts]
    Edit List [elst]
         trackdur = 18579   //same value which makes sense
Media[mdia]
    Media Handler Header[mdhd]
        duration = 92900    // huh ?
        timescale = 2997
many thanks
