I believe a partial match would only be useful if the partial match mapped to a unique record. My point was that the data points that seem to be the most unique to my computer seem to also be the easiest to change.

If I get a fingerprint that contains some super unique font and is requesting the site in Mongolian then yeah, that can probably be mapped to a single record.

If I get a fingerprint in which the only data points that match anything in my database are that the user is on a Mac using Chrome 76 and has cookies and local storage enabled, I don't see how that can be used to track a user.

My point was that the data points that seem most unique to a user also seem like the ones that change the most frequently. If you're only changing one at a time like they would during normal use, then yeah, it's probably still trackable, but if you wrote something to change all of them on every page load, I don't see how you would be able to connect one partial match to another.
