by mr. face's theorem (that usernotes did not exist more than 2.5 years ago), i have received 839 usernotes/2.5 years = 335.6 usernotes/year. therefore, an extrapolation of this line would lead me to believe i should have 839+335.6 = 1174.6 usernotes by this time next year. However, I figure that I receive usernotes at a much slower rate than that. The rate cannot be described purely by a linear curve. a sinusoidal curve would be much more apt to describe my usernote rate.
