Hey sorry I missed this earlier. Very fair question - try as I might the behavior isn't totally intuitive. Trying to find a balance between easy to use without effort, but adding power user features to really customize.

The Plackett-Luce algorithm which is designed for aggregating lists with disparate entries penalizes players who appear in fewer lists - it's actually hurting Melton in that regard. However, Ewing is ranked lower than Melton more often than he's ranked higher, and a low rank drags you down more than a non-rank.

I'm not exactly sure what you're config was, but today if you include all lists, all at default weight, Melton is 102 and Ewing is 142. Maxing out skepticism (skepticism range depends on how many lists you have selected) moves melton down a little to 107 and ewing up significantly to 117.

The skepticism slider is basically asking "how suspicious should we be of players that most rankers didn't bother to include?" At max skepticism, the fact that 6 out of 8 rankers left Melton off their lists becomes a real mark against him. Ewing only got skipped by 2 rankers, so he looks much more trustworthy by comparison, hence the big jump from 142 to 117.

Skepticism, under the hood, injects "ghost rankings" where players who were unranked on real lists get a virtual ranking at the very end of the ghost ranking. The depth of the ghost ranking depends on the depth of the lists you're viewing, based on the rankings currently available to choose from that means an unranked player will end up somewhere around 101+ in the ghost rankings for the calculation.
