Hmm, You may be right, reading it 4 more times for comprehension it
looks like it should be set to -1 not 1.

Not according to my man page:

       --modify-window
              When comparing two timestamps, rsync treats the timestamps as being equal if they differ by no more than the modify-window value.  This is normally 0 (for an exact match), but you
              may find it useful to set this to a larger value in some situations.  In particular, when transferring to or from an MS Windows FAT  filesystem  (which  represents  times  with  a
              2-second resolution), --modify-window=1 is useful (allowing times to differ by up to 1 second).
