you might want to look at Yassers book who goes down what appears to be the same lane as your self.
talso the recurrent sequence and cscales of Mt Meru are all continured fractions.
the continued fraction up the scenter of the range it appears you are touching up here was possibly done by Konerup
which i have an excerpt from here
