I wonder how many of the actually existing j-dramas/movies are listed here

Like, is there even a way to find out a percentage? Does someone have an assumption or even an answer?
My guess would be a proper 70 percent.

Your question is too difficult that's why nobody has the answer :P

What’s behind your question? Do you feel like MDL is keeping some titles off or that certain titles just haven t been uploaded yet?
