Presently we have 160 contacts that persistently appear in the "Possible Duplicates" filter who are clearly not duplicates.
Flitering on Name (or Names) only does not work, there needs to be a better filter.
My recommendation is to filter on the most persistant feild which these days is the mobile phone number. Names are common with the common surnames such a Smith, emails change regularly as people transfer to other ISP's but phone numbers persist.
There also needs to be a way to tag two names as not duplicates for when the filtering fails. All we can do at present is use the "Organisation" field so that we can at least identify the 160 "Not Duplicates" when we go to check and clear true duplicates, the alternative being to go through all 160 time and time again which would be a laborious and time consuming process
