# UPDATE: this example was rerun with Mergeall 3.3 and the new 
# preset, so its runtimes no longer include the prune overhead.
# See also PRIOR-SYNC/before* for a similar sync run before 
# same-name deletes were changed to run iff the names differ
# (spoiler: deltas apply fell from 27 minutes to 34 seconds).

# [Former caveat: this was run before the [BackupChanges = False] 
# config preset was added to avoid slow __bkp__ folder prunes.  With 
# the new preset, the apply step runs faster; most of its time here 
# was spent in a prior-backup delete, which is slow in Android 11.]
