I almost emailed Spey and CP about the same thing. Martin's ranking is basically from the fact that he beat Berge. Three of his 7 losses are to the top 3 guys, although the closest was still a 5 point loss to Kolodzik. You don't even mention Martin's non-D1 loss to the #1 guy in NAIA (who got teched 15-0 by #17 Olivias two matches later so not likely a top 20ish guy in D1). Martin's wins don't come close to offsetting his multiple okay to bad losses. He's 0-4 at NCAAs so not like he should get the benefit of the doubt a returning placer might.
I don't see Berge as much of a buffer between Martin and Mauller as his resume is fairly thin as well with wins over #13 Degen and #15 ven der Merwe, with a loss to #6 Finesilver to go with his loss to Martin. Heil, too, is fairly thin at #8 as his best wins are #12 Thomsen and #15 ven der Merwe, with his six losses breaking down as 4 to guys that are (or were for Zacherl) ranked above him, an injury default to #16 Lugo (down 6-0 at time) and then a “bad” loss to Blees.
I don't follow the reasoning, but hopefully they will shed some light on their thinking.
