It is from awesome miner but when I logged into the miners I saw the exact readings I was getting in awesome miner. Refresh your miner status page fast when you log in to see if you see what I'm seeing.
EDIT: It looks like when logged into the miner they only show average hashrates so when you first log into the miner after booting it you will see the high hashrates but as it averages out you will only see the average hashrate.
Don't worry about short term swings. Poolside hashrate is what matters and even that can have lots of variance if pool diff is high. Check after you've submitted 1000+ shares to the pool.
