How Does a pool’S Historical “luck” Percentage Influence a Miner’s Decision to Join?

A pool's historical luck percentage, which is the ratio of actual shares to expected shares needed to find a block, is a key factor for miners, especially those on PROP or PPLNS. A pool with a history of high luck (below 100%) is often perceived as a better choice, as it suggests higher payouts in the short term.

Conversely, a pool with a long history of bad luck (above 100%) may be avoided, as it implies lower, less consistent earnings.
