why does ipoker offer me the worse roi out off any poker software???

Ive played poker for 5 years and either the poker player has improved by 100% or im getting bad beats all the time from ipoker or im playing different (i know this is not the case playing my normal solid game)
But why oh why is my roi 100% worse on ipoker yes thats right 100 times worse i mean come on guys 100% worse thats unreal
My stats for the 14% is over 6250 games so the results are proven
But with ipoker i seem to drop down and down and down i dont know why but ive had sum really awful beats lately from them a one outer on the river yesterday
ill copy/paste my ss stats proof it what do you do wen a poker software provider is basically saying your a 100% worse player

Username Games Played Av. Profit Av. Stake Av. ROI Total Profit Form Ability /100 Network Filter
Brett25 6,242 $2 $13 14% $11,527 Hot 76 CryptoLogic x
brett26 1,106 $1 $9 9% $1,082 - 68 iPoker SNG Only x

What happens a lot with ipoker is the guy witht he most chips seems to win a lot and beat the shorter stacks a lot i cant figuare out why this software syas in 100% a worse player sumthing is vey wrong!! ive played enough games on the ipoker for it not to be variance ive got the HH form both and know im paying the same
So basically what ipoker is telling me there players are 100% betteer
ideas?
