For cc-pVQZ-F12 this produces errors that are slightly less than two orders of magnitude smaller than the orbital BSIE, but the only auxiliary basis that produces more accurate results is aug-cc-p(5+d)Z/JKFit, which possesses around 25% more auxiliary basis functions. For TZ and QZ orbital sets, the boxes corresponding to the cc-pV([n+1]+d)Z/JKFit errors become squashed, reflecting both the very small average errors and the small range of error.
