f2pool has introduced PPLNS as an option for BTC mining payout schemes. Users can now select between PPS+ (default) and PPLNS for their BTC mining on each mining account. The payout scheme can only be changed once a day, and will take effect at 00:00 UTC the following day. Please refer to this guide.

With PPLNS, the mining pool calculates mining rewards based on the actual blocks mined by the pool. The revenues will be influenced by the pool’s luck value. As a result, the daily mining rewards a miner receives may fluctuate significantly, while the long-term rewards are anticipated to be consistent with the theoretical rewards.
