1. I don't add hentai to my list because I don't think it belongs here.
2. My favorites aren't really sorted out and Code Geass is probably my favorite anime so far .I still didn't find an anime that I would truly consider to be a masterpiece and give it a 10 without any doubt . Code Geass really got me into anime and that's why I appreciate it (probably more than I should) that much. I watched a small (well I consider it small) amount of anime and manga and therefor my favorites could easily be changed.
3. I'm not a professional anime critic and therefor I grade my anime mostly based on how much I enjoyed. My ratings are still pretty low since my average is 5.6 atm.
4. I use the MAL grading scale and therefor if I give some anime a grade of 7 or higher that means it was really good and that I definitely enjoyed it.
5.I decided not to rate the stuff that I watched when I was a kid , that's the reason for unrated stuff on my list.Also,most of the time I won't rate specials or short stuff like that.
