Repeating patterns are very tricky with the rangefinder.  When I encounter
such situations, I do one of three things:

  * Try and find the edge of the pattern, or some part of it, which
    is unique and focus on that.  Then perhaps adjust a little if I
    can figure out the difference between the distance to that and
    the distance to the part I'm primarily interested in.  Basically,
    what you did.

  * Use sufficient DOF to capture the area and scale focussing.

  * Pull out an SLR.

The M is good, but not for everything.

M.
