I’ve seen some decode stretches in my day, but this one is kinda thin. I can’t see how extracting the “ha” from an extraneous “that” is relevant. I believe the delta to be of more importance.
My brain is limited and a lot of decodes are for deeper thinkers than me! It is funny that the “ha” is highlighted but who knows... that’s the first page of the doc, many more at link but I didn’t want to read legalese last night.
