It's minor channeling, but you can see signs of it on the right while the cone hooks to the left:

According to our resident chemist, this happens as the surface tension across the liquid becomes imbalanced (less surface tension on the right, more on the left). I would expect an extraction that long would be under
and overextracted, i.e., edgy on the front and sourish on the back. Splitting the shot into thirds would be telling. But hey, it's been quite awhile since I used a triple basket, so I'm due for some experimentation.
