Hi,
I'm guessing this is the result of a resurvey John has very recently finished of all the ranked peaks listed in his database, with the help of a program I wrote to identify incorrectly-identified ranked peaks. At the same time, he was also finding new ranked peaks with another program I wrote. This resulted in quite a few new ranked peaks, but also a few other peaks losing their ranked status, because another nearby peak was actually higher. For more information, see this thread:
