How Does a Miner’s Individual Hash Rate Relate to Their Portion of the Pool’s Variance?
An individual miner's hash rate determines their proportion of the pool's total shares. A miner with a larger hash rate will contribute more shares and thus receive a larger portion of the reward, but their relative exposure to the pool's variance remains the same.
However, a higher individual hash rate reduces the miner's personal variance within the pool's PPLNS window.
