There's two newish components to this:

Firstly Tim Daw's discovery that there are patches in the location of the missing stones. This evidence is a bit weak because this does not prove that there are stone-holes; just that there may have been holes prepared.

The second is the excavations under the A344: This may have revealed more evidence for MPP's periglacial theory. But it may not: You would expect these sort of formations regardless of whether or not the stripes found at the Avenue bend actually join up with the ones found under the road.

MPP also claims to be able to see "the big picture" and that this is a "missing piece in the jigsaw". It will be interesting to see what this means.
