Notably, in the short term, the PPLNS model is highly correlated with a pool’s luck. If the luck factor of a particular mining pool decreases in the short term, the miner’s income will also decrease accordingly (the opposite case of the mining pool being lucky in the short term is possible too). However, in the long term, the luck factor tends to average out to the mean. Hence, this model is ideal for fixing orders on a big pool that has a high chance of finding a block within the order time limit. Or a standard order which will have miners connected for a longer time.
