I watched one 名探偵コナン ep each, yesterday and today, so 264 and 265, and understood about my 60% or so.
I also decided that for February I’m going to try to do something other then watching コナン. 
So I’m starting a rewatch of Digimon Adventure 01 and 02. After watching the prequel movie yesterday and ep 1 today, I’m now also excited for the daily confidence boost - I was able to understand well over 90% of both!
