# Battles-based Stronghold RatingSRB

The Stronghold Rating with battle volume rewarded rather than merely gated, so a clan that has proven itself over hundreds of battles ranks above one with the same SR over twenty.

Also known as SRB.

[SR](https://unicum.gg/glossary/sr.md) deliberately ignores how much a [clan](https://unicum.gg/glossary/clan.md) plays. SRB takes that same rating and multiplies it by a term that grows with the [battles](https://unicum.gg/glossary/battles.md) behind it, so it can only ever be higher than the SR it is built on.

`SRB = SR x (1 + ln(1 + battles / 1000))`

Logarithmic, so the first hundred battles are worth far more than the thousandth.

One volume constant across every [tier](https://unicum.gg/glossary/tier.md), on purpose: [Skirmish](https://unicum.gg/glossary/skirmish.md) Tier X is played continuously while [Advances](https://unicum.gg/glossary/advances.md) runs in bursts a few weeks a year, so the tiers that really are played more earn a bigger bonus. It is the same idea as [HRB](https://unicum.gg/glossary/hrb.md) next to [HR](https://unicum.gg/glossary/hr.md) on the [Steel Hunter](https://unicum.gg/glossary/steel-hunter.md) board.
