It's tough to say since I don't know exactly how you've done these measurements, but my guess is that it has to due with how the profiles (assuming you have made profiles) are calculated.  Can you please provide us with the actual calculations you're doing that are discrepant?

Without knowing what "data" here is, or how you generated it, it's tough to say.
