Stale rate when using pools.

[Cryptoin]

I just wanted to verify I am calculating my stale rates correctly when using a pool.  I assume I am supposed to multiply my accepted share rate by the pool efficiency rate?  For example if I have 99% of my shares accepted and the pool has 98% efficiency I would have an over all efficiency of 97.02%.  Thanks.

No, your efficiency is usually your accepted share rate, in other words 99%.  Other miners may have a different rate for numerous reasons, so the pool's efficiency is usually the combined efficiency of all miners.

A few stale hashes is insignificant... The bigger issue is 'missing' hash power.....,

I use Eligius to benchmark and have noticed several other pools  'disappearing' hashing power.........
and no... it is not network latency..

Generally....
Invalids.. 0%~0.08%
rejects  0.8%-1%
