I've recently noticed the same problem. My stat bar shows a find count of 1334, but when looking at All Geocache Finds in my profile it shows Total Records or 1333. I think this discrepancy is responsible for different results on my milestone list as generated by different sources, Cache Stats (ver 3.0.6) and the It'sNotAboutTheNumbers having one list and FindStatGen3 V3.7.11 macro run by GSAK showing a different set of caches. I think if I can resolve the disparity in this Found caches count, all the milestone lists will spit out the same results. Any ideas if there's anything that can be done?
