I find the "Extremes-by-area" statistic very interesting. It's comparable to the GeoTrophy. Unfortunately, it doesn't take historical data into account.
In PGC, I only found the oldest, highest, most found, and most favorite in Denmark. However, I also found the northernmost, westernmost, and southernmost—at least as they were at that time. It would be good to include these as well, since the statistics otherwise constantly change.
