My comfortable reading speed of Spiegel articles is about 40 words per minute. Writing out just one word, I finished reading the below-mentioned article of 522 words in 13 minutes. (calculation based on today’s article in Der Spiegel “Entschädigung für Naziverbrechen: Tsipras wirft Deutschland Trickserei in Reparationsfrage vor” (http://www.spiegel.de/politik/ausland/griechenland-tsipras-macht-reparationen-wieder-zum-thema-a-1022876.html)). In English, the speed is about 118 words per minute. But usually I tend to choose tougher articles. And there’re plenty of these in Der Spiegel. When my vocabulary reached 10400 German words (from what I could read in the Internet at the time, that number of words should have been sufficient for most purposes), I decided to check how well my German reading comprehension fares against sample texts in Goethe-Zertifikat C2. The experience was eye-opening and convinced me 10400 German words are very far from being sufficient (text “Ich bin Lehrerin” on page 4 (http://www.goethe.de/lrn/pro/c2-neu/C2_Modellsatz.pdf)). Some articles in Der Spiegel are at least as difficult as “Ich bin Lehrerin”. Now, with 15590 words I still feel I need to know more words. Of course, for some people that may be more than enough. But, in my opinion, it’s not enough to read German press fluently. Speaking Ukrainian/Russian does help in guesstimating some German words, albeit probably not as much as Norwegian, as you suggest.
