This is a copy of a post I made in the multipoo.in thread:
The concept of this pool sounds great, but since a good portion of the pool appears to not be using the auto feature, wouldn't the use of PPLNS cause miners to lose money since they are bouncing around from coin to coin? It seems like this would be much better implemented using PPS.
Let me give you an example of the bouncing effect.
ARG network hash rate was a low 10kH/s, at block 54,501, so the difficulty dropped, as it does every 250 blocks, this time from 0.85 to 0.2 this made ARG jump up to just over 600% profitability, which made multipool.in hop and suddenly add over 320kH/s to the hash rate, an increase of 3,000% plus whatever other pool hoppers elsewhere did. Since the next 250 ARG blocks were found in minutes, the difficulty jumped back up to 0.85, multipool pool bounced again, leaving ARG with a network hash rate of around 17kH/s currently, and a block time of many minutes instead of the 32sec the coins difficulty target is designed for. This is not fair on the supporters of ARG.
My suggestion is either let the miners keep some hashing power on ARG by opening up the direct port again, or take it out of the multipool rotation. multpooli.in represents >51% of the ARG nethash when the miners are pointed to it.
Pool bouncing is hurting the coin.
