By default, rsync considers a file to be the same if it has the same
size and the same modified-time, so it is possible for two files that
match in these attributes to differ in contents.  If you can figure out
what changed the spreadsheets without tweaking the files' modified-time
you might be able to fix the problem at that end.

Since you say that these are just the .xls spreadsheet files that have
this problem, would limiting the rsync -c to just the spreadsheets make
it workable?

  /usr/bin/rsync -W --progress --rsync-path=/usr/local/bin/rsync -e ssh 
    -c --delete --force --include='*/' --include='*.xls' --exclude='*'
    -av /data/ machine2:/data/machine1/
