It's a pain in the &^&$&^ there's over 3000 bars and 1h:45mins of material.
I can reverse engineer it with a video audio sync app, the top contains the original RTs the sections are the generated RT split into chord name items, the app syncs them to the same time in the source audio.
Some of the bottom items did not sync as I suspect they were transposed even though the song setting were set to Avoid Transpositions in RealTracks.
The ones above at the same position may be chord substitutions.
