What is LwRC+?

During a match, the gold graph tells you which team is ahead and by how much. It doesn't tell you who built that lead. LwRC+ is our answer to that question.

What the name means

LwRC+ stands for LoL weighted Resources Created Plus: the resources a player created, weighted by the game state they came from, and compared with the average. The w in the middle stands for weighted, and it is always lowercase.

LwRC is the contribution itself, measured in gold. The + turns it into an index where 100 is the average.

Baseball has runs. LoL has gold.

Baseball games are decided by runs, so modern baseball analysis starts with one question: how many runs did this hitter help create? In LoL, we put gold in that place. Kills, objectives, towers and farming almost all turn into gold, and the gold gap moves closely with who wins. Teams very rarely win while behind in gold.

How we value a single play

LwRC+ asks one thing about every play: how much did it change the gold your team is expected to end the game with? Say a dragon steal lifts your team's expected final gold by 1,100. That steal was worth 1,100 gold. Nobody decides what a dragon is worth. Thousands of similar game states answer that.

Gold you earned, and gold you denied

A roaming mid gives up their own farm to make plays in other lanes. Their wallet gets lighter, but their team gets richer and the enemy gets poorer. LwRC+ counts both: the gold you added to your team's expected total, and the gold you took off the enemy's. When you die, the cost comes off.

100 is average

100 is the average for players in the same role in the same season. 120 means 20% more gold contribution than average, and 80 means 20% less. Because players are only compared within their role, a support who spends little gold can still top the chart.

Live, then final

LwRC+ moves during the match. Numbers shown live are provisional, and they are finalized when the game ends. Only final numbers go into season records.

Every number has moments behind it

Behind every LwRC+ are the plays that built it. Tap a number and you go straight to those moments.

LwRC+ is RORR's own metric, calculated from match data. It is not an official record. Curious how it's calculated? Read the next post.
