And I'll admit, I haven't explained it at all.

Each column is a release, mostly LaserDiscs, except the newest version of that spreadsheet I've inserted a column for Video Collector's ESB_TP also.
Each row is, or strives to be, the same frame of film.
In the GOUT column, those are the frame numbers you'd see in Virtualdub or Avidemux for example, with STAR WARS title card appearing at 688.
For example in GOUT 15585, you look for a '7' pattern beside R2, formed by motion blur in the snowflake trails.

Other columns, those are the frame numbers (actually more akin to 'frame labels' which we talked about briefly in another thread) that you'd see if you turn on your LD player's on-screen display, while in freeze-frame mode.

Yellow cells are missing frames, in that release, or half-missing in some cases.
JSC is missing the most (6.5 frames, or 13 fields) at that first 1000-ft reel change shown in the example.
Both SWE pressing (Techinidisc & Pioneer) are quite similar here, missing exactly the same frames/field although the labels are skewed.

There's more to it, regarding telecine cadence (which frames are 3's and which are 2's in the pulldown pattern) that I'll try to explain later, maybe in my 'reel change' thread.
Earlier in this thread we wondered if JSC & SWE are from the same source?
Well, if their respective pulldowns are out-of-step, they cannot be from the same telecine session.

Anybody interested in hearing more, or will I have no choice but to cancel this project? </offTopicJediTrayRefernce>
