Your graphs need work. What you've got is a series of linear ranges at different orders of magnitude. The peak in the middle of the x range is probably smaller than the Forrst peak, while the area under the HN peak is probably larger than everything else together. The graph does not communicate any of this clearly. If you want to do pseudolog, use 1-2-5-10. But if you're using Excel, you can just right click on the axis, choose format axis, and tick "logarithmic scale."
