No p2pool use PPLNS.

Payouts are not based on shares since prior block but shares in a set number of prior shares.  All shares which are paid out are worth the same.  It can't be hopped*.

Simple version is hoppers exploit the fact that each block reward is split among a VARIABLE number of shares.  So when number of shares is small the reward is worth more on a per share basis.  When the number of shares is large the reward is worth less on a per share basis.  This dynamic only exists in prop pools.


*Technically there is a very small and slight window when difficulty changes but it is mostly an academic risk.  Some pools like Bitminter use shift based PPLNS to reduce even that small vulnerability.

Isn't p2pool not a perfect target for pool hopping?

Since all information is available realtime (when a block was started, my actual share, ...)
