Curious that this doesn't look exactly right, the left/right shift seems
enough based on the apparent displacements of the dart fins against the board.
When I see it in stereo it's flat, which kind of goes with what you say about
using 1cm instead of a wider 7cm, so maybe 3cm would have been better.
  The way I use to see these is just hold my hand flatout and aligned with my
nose between my eyes and angle my hand enough to only be able to see each
picture with the corresponding eye, closing each one at a time to be sure I have
only the full left or right image in view.  Sometimes I don't need to do this at
all for the small pictures or just a quick hand divider for my eyes for others.
I think another thing to keep in mind about it is these can be fairly deep 3D
and require some focusing.  By that I mean there can be near and far parts which
have to be looked upon as separate parts, otherwise you don't ever see the whole
picture forward to back "in focus" without actually looking at those parts
alone.  This can make for a seemingly distorted and nonmergeable stereopair.
Probably the predominate factor with this particular rendering.  That in mind I
believe it needs the wider camera separation.
