Ook, SORRY if i was wrong taht is not your pool.
I sawed this twice so i was thinking it was yours.
What's "it"? I mentioned several pools.
In case you meant Multipool then I guess a clarification is in order.
Most pools use the proportional system, which is vulnerable to the pool-hopping cheat. So far this has only been a problem in theory because hopping wasn't rampant. Multipool is a recently opened meta-pool which forwards its participants to proportional pools in a hopping pattern. This means that:
1. As long as Multipool is working correctly, people who mine for multipool will receive a higher reward on average than solo (as opposed to any other pool which is at or below solo levels).
2. Now that Multipool exists, proportional pools have a much more serious hopping problem, and this may cause a noticeable decrease in the rewards of those who mine for them.
