This time round after 6 weeks I've hit 110h, a little more than half of which I spent reading. Reading Russian is definitely a lot harder than French. After a similar amount of time spent on reading I was almost done with the first Harry Potter in French and had 6000 known word forms in LWT at a known / unknown ratio of 69% in the database. With Russian I'm reading at barely half the speed still and I'm only at ~3500 known with a ratio of 46% known. Ouch! Every now and then I encounter cognates from German, but other than that there is next to no vocabulary overlap with the other languages I know. The sentences are usually longer and more complex with a rather annoying number of verbs too. In fact on every page there is at least one sentence that is much much more complex than anything I've encountered on Duolingo, Assimil or Clozemaster so far and it's unlikely that such sentences will come up at all, because they go on for half a paragraph
I also feel that no amount of courses could ever give me enough vocabulary to bridge that missing cognates gap that makes reading feel so much more difficult. That said, by now I'm starting to figure out how Russian builds longer words from shorter words that I already know, which suggests that I might be on the verge of a jump in comprehension. Speaking of a jump in comprehension: With the Ночной дозор audiobook I'm starting to follow the story pretty well although I get maybe only 25% of the words. Before I started to learn Russian I had this strange skill to always know what people are speaking about in the language although I didn't understand a single word - my parents tried to have secrets from us in Russian, so that's probably how I developed that skill of subconscious understanding. Right now it feels like a very enhanced version of the same thing with the occasional fully understood sentence. Still a lot of guesswork going on, but something is definitely happening and coming together. Not sure how many pages it will take me to get to my goal of 35,000 known word forms in LWT and whether that will even be enough to start with extensive reading. I suspect 5000 pages might actually not be enough after all - it got me to 29,000 in French which I was picking up much faster. I guess it will have to be a double Super Challenge and if I hit 35,000 with a ratio of less than 85% known vs unknown I'll just keep going. So, if after all of Belgariad I still feel I'm struggling a little I'll just continue with Terry Pratchett translations.
By the way, if I read all of the Belgariad and some Terry Pratchett my reading progression in Russian will actually closely mirror the books I read in German when I was about 9 or 10 years old. No wonder that I was always way ahead in reading comprehension considering that I powered through all of the Belgariad - 4000 pages - in one summer! I only realised the other day how exceptional that is, since these books are not actually meant for children and even kids who like to read only get through such amounts in secondary school. So, to reach my level of reading comprehension as a 10yr old I will have to read about 10,000 pages at least in any new language
To match my 18yr old self I'd probably need around 100,000-150,000+ pages. I have always been a voracious reader. In fact I once had to ask my brother for money because I was completely broke after spending way too much money on books. He couldn't help though, because he had just spent all his money on records. He did have stamps though, so he sent me Knut Hamsun's Hunger which is a book about a starving writer 
In any case, these numbers totally explain why my Spanish reading comprehension is so laughable and insufficient for my standards, I'm not even at the level of my 10yr old self yet! So, right up top on my Spanish to do list is a full intensive reading SC with page turners - depending on my progress with Russian I might have some Terry Pratchett left or maybe Hunger Games followed by a few Stephen King novels. Also, the Girl with the Dragon Tattoo.
Other than that nothing to report, still making next to no mistakes in the exercises and some sentences are more difficult to pronounce than others. I tripped over the combination of что же for example although it's so close to тоже! I think they put tongue twisters with lots of rolling Rs and combinations of ш ж and ч in there on purpose. Good practice! On Duolingo I'm only 4 skills away from the last checkpoint. I'm approaching the final stretch! I also seem to be making less mistakes during production these last few days. On Clozemaster I seem to be getting all the insults right (multiple choice) which amuses me to no end. I do remember those from our Russian (mafia!) neighbours living one block up the hill. I guess my childhood left me only with the most "useful" bits - animal sounds and insults 
Such feelings tend to increase whenever I have to deal with German taxes or any other kind of tedious bureaucracy like university paperwork. On some days I longingly think back to my university days in England when I was just starving and cold rather than having my sanity challenged by this veritable "place that sends you mad"
