Today the “mini” p2pool had the same hashrate than the normal p2pool 451 MH/s

As the hashrates currently fluctuate by around 100 MH/s daily, the mini chain should have a higher hashrate tomorrow than the normal p2pool chain.

The fact that the mini side chain has a higher hashrate than the p2pool main chain is likely to cause confusion for some time among older miners.
