In Band Percentage From OSA

Hi
I'm using the 86142B to measure the percentage of power from a laser within a between 930-950 nm. I use the wavelength markers to get that power between 930 and 950 then divide that by the total integrated power.  We also save the total spectrum to csv.  The percent of in-band power from the two OSA values is different than what we get when we sum up the spectrum points in excel. Any ideas as to what I could be missing?
