Gold Diff

Win withcontext.

Gold Diff is a League build lab for people who want more than win-rate bait. It reads item order, rune pages, shards, boots, and spell pairs through contextual MWPA so the site can tell you what actually held up, not just what showed up in already-winning games.

Win rate bait is not a build path.

An item can post a 58% win rate and still be a trap because it only gets bought in games that are already won. Gold Diff filters that noise by comparing every build choice against a contextual baseline, not against the global average.

What it reads

Context over raw numbers.

Ordered items

Path scoring stays slot-aware.

A third-item read only compares against games that reached a third item. The site stops rewarding late purchases just because those games were already winning.

Rune pages

Runes are read as a page, not a keystone.

Primary tree, secondary path, and shards are all sampled together so the rune read still reflects real pages people actually ran.

Role hygiene

Flex picks stay visible without becoming noise.

Meaningless edge roles are filtered out, but champions with real off-role usage still surface when the sample actually supports it.

Scoring flow

A product-shaped way to explain the math.

Full methodology

Anchor the baseline

Gold Diff starts from the champion's own sample, so Ahri mid is not graded against random support or bot lane fragments.

Follow the order

Item paths are evaluated as first, second, and third checkpoints. Order matters, because real purchase timing changes the signal.

Stack the page

Runes, shards, boots, and spell pairs add directional context on top of the item path instead of pretending one stat explains the entire match.

Boris check

Don't let Boris cook.

One page to test item order, full rune pages, shards, boots, and spells, before Boris talks you into something cursed. The composite signal tells you whether your loadout outperformed the champion's contextual baseline, or whether you just got talked into a pretty tooltip.

Composite MWPA

All build components stack into one directional read.

Slot-aware paths

Item order is scored at each checkpoint, not in aggregate.

Full rune pages

Rune scoring uses real page combinations, not isolated picks.

Live roster

Champions already in the lab.

Each champion page lets you assemble a full loadout with item path, rune page, shards, boots, and spells, then read the composite signal before you lock in.
