I have been finding ways to look up the information for my own statistics tracking. GSAK is/was great, but I have been moving away from it. I have yet to find a way to figure out the days/dates with the most finds I have. I have used the GSAK macro Finds Per Day which did exactly what I needed it to. It would list every day/date I have cached and the number of finds on that day/date. I don't see a way to figure that out with Geocaching.com or Project GC. Is already possible? Is it something that can be added as a feature.
FWIW, I am working on having a day with finds 1-100. So a day with 100 exactly, 99 exactly, and so on.
