Universe a Dodecahedron?

Everybody has seen the story by now that the universe may be finite and wrap around itself, with the dodecahedron shape suggested as a model (though I'm still not sure why).

OK, look at the story, and in particular look at the critical plot of data vs theory. The data fits the theory well except at a single point--the left-most point. The plot doesn't give the error estimates, which is deeply unfortunate, but from the way nearby points deviate from the curve I have to guess that the systematic error is substantial. Without that point the data is quite in line with the "infinite universe" theory, and even with it we aren't given an adequate estimate for how much the data differs from theory.

The soccer-ball universe hoopla is a bit overinflated, given the data I've been shown.
