I am also getting lower then the coinwarz estimates, but each doge block has random value of 1-1,000,000 shares in them. So if you get lower somedays it should balance out on others. Coinwarz Calculator bases calculation on 500,000 doge per block which is average of 1-1,000,000. Thats why its never accurate on per day basis.
I agree but usually it's about 10% less that Coinwarz but last day it's 30% less, and not only at this pool - my second rig is mining at another pool and I got the same results from it. IMHO now to mine dogs became just the same like to mine ltc directly. May be the situation will change another day...
