Apologies, I should have been more precise.

Please use that command next time you need to run an apt update and when
you get a run where you should have had PDiffs but did not get any, then
submit the log file for that run.
  The log file provided is for a "no-changes" run. Accordingly, I cannot
tell if it skipped PDiffs or not because it concluded there was no need
for an update at all.

My rule of thumb is more about length and whether the mail programs line
wrap long lines. :)  For mail programs that don't, "short" inline
copy-paste is often nicer, but for long files or zealous line wrapping
attachments are often more readable.
