I think that makes sense. They're using the IRS list of the 400 richest tax returns. I think when you're making money at that level you can hire enough tax attorneys and accountants to make sure your actual taxable income is not among the 400 highest in the country unless you have some major event like selling a company. It would make sense then that there's a lot of turnover in that metric.
