How this head-to-head is established

  1. This pairing exists only because at least one of the two articles' own results tables names the other fighter. No matchup on this site is speculative and none is a hypothetical.
  2. Every figure in the comparison below comes from that fighter's own page and carries the same source line. A dash means the source states nothing, not that the value is zero.
  3. Common opponents are found by matching linked bout lists, which is only possible because every fight list here is linked to every other. A shared opponent is not a transitive result and this page does not treat it as one.
  4. Nothing on this page predicts an outcome. It is a comparison of what is on record.
