I have noticed that your home page  BTC/GH/Day https://miningpoolhub.com/?page=home&normalize=none

Does not match the jason/api link https://miningpoolhub.com/index.php?page=api&action=getautoswitchingandprofitsstatistics

that miningpool MultiPoolMiner uses. 

For example at this moment

Ethash on your home pages 0.03154 BTC/GH/Day but the getautoswitchingandprofitsstatistics is 0.03180189 BTC/GH/Day
Scrypt 0.03140 BTC/GH/Day vs 0.04184262 BTC/GH/Day

Why is this? I am using No Norm.
