Value in Categories mode is the sum of the selected categories' z-scores (how many standard deviations above positional-neutral, per game) — the standard way to value across roto categories. Points mode ranks by your custom point weights. xGΔ = goals above/below expected: a HOT finisher is a regression / sell-high risk, a COLD one is a likely buy-low. +/- is a 5v5 approximation.
