At least in here I'm matching the low points of the waveform. It's not whole decades matching though.. so.. I don't know.. What you gotta do is go with where the bottom points of the waveform match up. Then had whatever decade points that was.. and matched those. So.. something there, I bet. lol. But do these low points back in time match. I don't know.. that's your fuckin data. haha
