You’re faster than me - I’m averaging 18 days/level, and getting slower as I go along. I think what makes it feel slow, is if you already know some of the kanji and vocab, but are being forced to work through the SRS system for everything anyway.
Of course, “good level completing pace” is pretty subjective measure, which is probably different for everybody depending on how much time they have available for studying.
