Two important characteristics in identifying valid Inverse H&S formations are Symmetry and Volume Trend. The volume trend in this Inverse H&S makes it suspect, IMO, being the reverse of normal; that is, higher on the right shoulder than the left. The symmetry, while correct in time (equidistance from the head), is off in that the shoulders should be roughly at the same depth, while here the right shoulder is much shallower than the left, and rounded, while the left is sharply pointed.
While neither of these characteristics would, IMO, invalidate this IH&S, I believe they warn that the formation might not play out as anticipated. JMO FWIW, but WTHDIK.
