The pulse-period argument for trusting the settle-time run is withdrawn, and the port authors from those numbers so it belongs on the page they read. The plate delay survives because it agrees with three independent prior readings; the menu build-in and B-to-title are anchored by nothing, so a few per cent of emulator slowdown sits inside them undetected. That is a second, independent reason to treat those two as provisional beyond their being one-run figures.
