I don't know what the recommended trace smoothing is...but if you use 1/3 or 1/1 you should see a better picture of the average. You should also set the limits of the graph to the following: Top=105.0, Bottom=45.0, Left=15.0, Right=200.0. This will give you a better picture of your low frequencies only. You then want to set the graph size to 800 pixels wide.

It also doesn't look like you have your 80Hz crossover in your reciever on, but you have the target set to Bass limited with a 120 or so cutoff? Which speakers are playing when you took the measurements? Do you have a sub? Towers? What kind of mic are you using? I'm not sure why you have the the target line sloping down like that at 80Hz as it seems you have a full range signal. I'm guessing you are using tower's that are set to large...if so set the target to full range and set your graph up like I explained in paragraph 1. There is also a thread that explains this.
