You might want to read Erwin's excellent article on rangefinder accuracy, or
just skip to the conclusions!  ( )  As I recall, accuracy of the
0.72 really only became a factor with the 135mm 3.4, which was marginal with
that lens wide open.  Plenty accurate for the Noctilux and 75mm Summilux.
Intuitively, it seems like the fastest lenses would have the biggest
focusing problems, but actually, it is the longest focal length lenses, even
though they are slower -- the rangefinder base length is smaller relative to
the subject distances with the longer focal length lenses, for a given image
