Does a Very Large Pool Experience Less Short-Term Luck Variance than a Small Pool?
Yes, a very large pool generally experiences less short-term luck variance than a small pool. This is due to the statistical law of large numbers.
A larger pool's total hash rate provides a more consistent stream of shares, making its actual block discovery rate more closely align with the mathematically expected rate. Smaller pools have higher volatility in block discovery, leading to more extreme periods of "good" or "bad" luck.
