Not sure that you guys rewarding miners with PPS ratio shown on your webpage. While doge price relating BTC is going higher as well as your PPS ratio, my wallets geting almost same amount of LTC per day. I am comparing prevoious fluctations of PPS ratio with rewards of my wallet. Hashrate of my miners did not change. Same amount of rewards either PPS ratio 340% or 380%.
You are probably not taking the network difficulty into account. The PPS ratio went from 340% to 380% recently, but during the same period the network difficulty also went from 8918390 to 9917510.
At any rate, you can see a detailed breakdown of how your rewards were computed if you click on the "View full history..." link on your account page and then scroll down to Lifetime Rewards History.
