Hi @Dave-Hicks, I use Sound Forge Pro's 'Statistics' tool to measure ATSC A/85 loudness for broadcast submissions (-24 LUFS) or web streaming (-14 LUFS). The tool is much, much faster than real-time of an entire program or segment. The tool displays LU, dBFS and RMS, LU measurements include, Integrated, Range, Momentary, True peak, Short term. Integrated, being the most important for b'cast submissions.

Sound Forge Audio Studio does not have the LU loudness factors.
In case you are not aware, BorisFX acquired Vegas, SF and Acid from Magix a few months ago.
