A strange rally in Ether?

This rally is difficult to count. Overall it can't (yet) be called impulsive, so I suspect it's wave B of a correction. My best guess so far on counting it seems to be to call the move from the A wave low a double zig zag with the final (?) C wave being an ending diagonal. I would expect the 5th wave of the diagonal to throw over the top of the pattern slightly - which would be normal. If correct, this would mean it should be followed by a 5 wave move to the downside to complete the correction in wave 4 (of several degrees higher). Maybe a final wave 4 low of around 11.50?
Like I said I'm finding this difficult to categorise....does anyone have any other thoughts?
