As a pool, we are not able to accurately know the exact work rate of each individual miner. The method we use, is based on the number of shares and difficulty your miner is mining at, and then guess-estimate your hashrate based on the amount of shares you have submitted. We have a slight bug with our Rejected Hashrate which we are looking into, but our payouts only take into consideration the amount of accepted shares, and their difficulty, you have submitted. I hope this clarifies your query!
Thanks for getting back to me!
I guess my query is more at a practical level.
As an example, if you were exclusively mining Dogecoin, would I be better off:
a) mining directly to a Dogecoin pool which reports my having a 1.1MH rate
or
b) mining for altcoinplex which reports my having a 0.7MH rate
IMHO, in this situation they should pay-out the same amount but I'm concerned that I would lose out using altcoinplex due to the lower reported rate.
