And for each analytic iteration one of the fixed points is a singularity.

Why wouldn't you have a singularity at both fixed points? I didn't realize what you were saying here, but now that I'm looking at it again, I'm not quite sure I agree.

Edit: Wait, try taking the rslog relative to a number in the interval (2, 4) for base sqrt(2). I usually use e or sqrt(, but for testing purposes I don't think it matters.
