Interesting. Down through 1300 was pretty straight forward. 1200 slowed me down a lot. 1100 I could only get a couple of sentences from, at first straight read-through, but it looks like I should be able to read it by going carefully through it.

Background: Fully understands Scandinavian languages (native), can read a bit of German and Dutch, proficient in English, and can read a fair bit of Icelandic. All of this seems to help.
