I try to keep it updated several times a week (usually after I catch up on simulcasts). I also try to objectively rank things +/- 1 for my personal enjoyment. For example I gave clannad: after story an 8 because I really didn't like, 9 would have been neutral (9 is essentially the top) and 10 would have been if I had actually really enjoyed it.
Usually I watch at least 10+ simulcasts a season and ranks on those tend to fluctuate throughout the season. Do note that just because something gets like a 6 or a 7 doesn't mean its not worth watching since I don't rank purely based on enjoyment (for example, I looked forward to Rokujouma no Shinryakusha!? each week but only have it at a 6, MAYBE bumping to a 7 if the conclusion is really good).
Basically if I give something a 5, I found it painful to watch. Rule of thumb being if I give it at least a 7 (average) then it's probably worth watching, if I give it a 6 it's maybe worth watching.
I'm slow like a turtle. Plz no bully, I hide in my rock hard shell.
