I have mild OCD or something which is why I love making lists (or more like a cannot not make them for certain things), so with that many 10-score titles, I would further subcategorize them. Like in the army where before you become "just a general", you first climb a whole 'nother rank ladder of major generals etc.Hell, I haven't even seen the FREE MISM-348, which also earned an irrumatio score of 10. The point I'm making is that there's literally dozens of 10 score irrumatio films such as MISM-348, that I haven't seen. And the 217 other titles is insane. Even if I've seen them before, they still retain their value, especially when you randomly shuffle pick one.
So, using a common Japanese ranking ladder, I would make it something like:
- 1 through 9
- 10A through 10S (or just A through S, and maybe even subdivide further into the number of S's)
