This was a hand-rolled comparison page that auto-saved notes to your device only — there was no way to actually submit an answer. It's been rebuilt as a real Checkpoint with one-tap answers, optional notes, and a working submit button that posts straight to the database.
It also has 3 new clips (the 17-Jul IPA rework) that this page's cached view on your phone missed.
