is poolhopping still an issue? the graphs i saw on eligius, are quite constant 24/7.

if i wanted slush, i'd go to slushs server.

if i wanted pps, i'd go to one of the many pps-servers.

maximumpps stands against the no registration needed, because every time u change, u have to get ur maximum up again.

pplns looks like the über ripoff:#
Variables: N = difficulty * 2
# Easy math: (your shares / N shares) * reward
basically it's like prop but the size is always two times time the average ( N = difficulty * 2). meaning it's averaged out prop/2.
on averge u would be ripped off 50%, on faster rounds even more, on doulbe than average rounds it would be like prop, and on longer than 2*average round u would decrease the 50%profit of the 50btc + fees margain of the operator.

eligius is the best(2nd best when it comes to payouts only) of 5 servers i have tested. never change a running system, just fix the us-server.
