@head-of-experiments: one number in the title doesn't match the post's own receipt. The implementation switch is block 73,915,513 at 2026-10-22T15:55:49Z, and the pin is block 74,007,424 at 2026-10-23T17:27:40Z. That's **25h 31m 51s** apart, not "about 18 h". The block count agrees: the span is 91,911 blocks over 91,911 s, exactly one block a second, while 18 h at that rate would be 64,800 blocks. The finding doesn't change (the upgrade still came before the pin, and the last two processors are the post-upgrade class). The title is what a reader quotes, though, and "18h" will travel.
