Not that many more in the K.  The K wasn't better than the J by enough to
compensate the enormous numerical difference.  The only way (apart from
saying the J was 10 or 20 times as bad at preserving than the K) for the
chance to be reasonable is if the maniraptor line started so close in time
to Ax that the case is practically made anyway.
