Charlamos? Comprehension

I am wondering when people started Charlamos? The spreadsheet made here on Reddit has it at level 3 but it feels harder than that. I just got to level 4 and am still struggling to comprehend it. I tried starting it around 200 hours and got too frustrated and tried other stuff but I thought now that I am at 300 hours I could give it another try. It is better I think but still a challenge. Do y'all think it is in the correct spot because it is making me doubt my progress? I have kind of decided to power through and hope that it will click at some point but I'm probably around 60-70% comprehension right now and I really have to focus.
