I added a vinyl medium, using a similar CD-R medium as a starting point (for the track and artist titles only). [1]
I had earlier applied a TOC to the CD-R medium, [2] yet ModBot, soon after adding the vinyl release, decided to apply the DiscID's track times to both mediums. [3]

I don't think this is appropriate behaviour, considering that there may be minor variances in the track times between similar mediums. In this case, I suspect the CD-R's first track is two seconds longer than the nominal track time found on the relevant official album and single releases.
