Your method is going to fukk up the ratings.
Not for ur anime leader board or my personal anime list just saying I can tell which ones are 8 and above for me that I can finish and rewatchShyt I agree with @twan83 wholeheartedly
7 and below I doubt i finish them unless its interesting enough and just falls flat later but I can give a rating to a show even if I don't finish
Too many damn shows like I said most dont hold me down this shyt not gonna interfere with my light novels and manga where the piff is endless
