We do have that recorded.  Of 10,561 signatures for which the body hash failed, 8,219 (77.8%) appeared to be list traffic (i.e. had a "List-*" header field or a "Precedence: list" field).

Breaking that down further:  Of the 8,219, 6,614 (80.4%) were author domain signatures, so the rest were presumably list signatures (or something else).

57 of them failed even in the presence of an "l=" tag.
