MAF values - Is this wrong

[Illusion-Paul]

I have just done a log in my car to see if my MAF is playing up and this is the values i got:

It was done in a 4th gear acceleration.

Mt question is that i have seen another MAF graph and the actual goes a lot higher than requested, however mine doesn't ever reach the requested value.

Need to find a solution to the slightly poor MPG
