Herne Hill Saturday Training

Yup, almost impossible to set up Sphincters to fit with in the rules. Though the "The area of the point of support of the hands on the handlebars is defined by the diagram below:" makes it a little ambiguous (you could maybe argue the point of support falls within the box, even if the entire bar doesn't). Doubt you'd ever get picked up on it unless you race anything big.

You could argue but the UCI interpret the rules as the structure which supports the hands fitting within that area.
I have it on good authority that the UCI will be bringing their testing jig to the LFGSS track 'day' in 2013.
