Is DR available as a field

I would like to run MP3Tag to retrieve Dynamic Range to put in the Directory without running the DR utility in Foobar , is this even possible?

Regards Mark

It's only available if you choose to write DR metadata to the tags (via foobar2000's dynamic range plugin). You can see the fields via the extended tag dialog at Alt + T and use the field names where you like.

Mp3tag can not compute the DR data by itself.
