     In response to your message ... 
PH>> The surprising thing (to me) is that the critical point would be r(0) = sqrt(3).
OG>There is another critical point, namely 2  : the r1 results happen for sqrt(3) < r(0) < 2
Good catch!  You are right, when r(0) >=2, the limit settles down to r1 again. 
OG>There is the corresponding process with ceiling instead of floor, which is more unstable
OG>(many critical points between 1 and 5) again oscillating between two limit values

I find these constants interesting.  The continued fractions of k*r3 and k*r4 (for integer k) look intriguing also.   
Thanks for your analysis!
