Started mining on this pool and my discard rate percentage is crazy.

Getworks   Accepted   Rejected   Hardware Errors   Utility   Discarded
337           39           9           0                   1.765           669


scan time = 28
expiry = 7
queue = 1

even at queue 0 it was this bad.. tried 30/30 on scan and expiry and no diff..

is this normal for the pool ?
