I was wondering why upgrading my equipped tier hands to item level 263 would be a way bigger upgrade than my eqipped head despite the hands having a smaller stat-budget than the had and both having my best-stats.
This is because of the “set bonus prediction” option. That option ranks the upgrades assuming you have the full 4pc set. In that case, the gloves, which are a set item, would be a better investment.
You can turn that option off and see a ranking that ignores whether or not the items are set items.
