Don't forget also the delta time between US database, your local time and the frequency of refresh.
Have in mind that some processes (see other documentation) could take few days up to few week if you make a change on an old log (adding a favorite point, adding a log to an already archived cache, etc ...)
Be patient and if persiating, indicate points of reference for the investigation, cache found on which date&time, or modification done at date&time (with precision of date&time of the geocaching.com server or your local time)
Hope it helps
