I already told you hours ago that they used Congressional legislation as their measure. You even responded to that postNo, but my reading of what you have said in this thread is 100% accurate.
And again, you shared a chart while having no idea how they came up with the result. I asked you a couple of times to share it, and even questioned it and you've just ignored it because you found something from WaPo--I know the chart came from a book, but you linked it from that site--and don't know how they came up with the figures.
