I am having the same issue. I had to make a spreadsheet to add up all the columns in miningpoolhub. Awesome miner shows $6-8.50 as daily earnings but it is closer to around $1.50 - $4.50 depending on what stats you go with (they are constantly jumping back and forth).
The MiningPoolHub interface is very poor and hard to see what you are actually earning. I am not sure why they can't show more consistent stats instead of coins going away and coming back, along with amounts going back and forth as well. They should add something to convert to USD and then show a grand total. Right now I think people are making much less than they think they are.
What is your profit switching setting, statistics to 24 hours? Long switch intervals? Switching threshold? MPH don't like pool hopping from what I've read, you'd forfeit a good portion of your mining shares if you make frequent hops.
For something to ease your spreadsheet work and convert to USD and showing grand total, somebody posted in this thread or some other thread I don't remember, but feel free to try...miningpoolhubstats.com...since you are talking about using MPH
