> The first period includes within it a perfectly flat period longer than shortest of the periods you chose followed by a period of equal length that is more consistently increasing than the (mostly flat) period you've held up as an increasing trend, and then a period nearly as long as your shortest that is as consistently and more sharply decreasing than the one you hold up as showing a decreasing trend.

It sounds like you're referring to the "maximum tax rate on long term gains." As I stated, I used the "effective capital gains tax rate," which is the average rate that is being taxed (long term cap gains tax is different than short term).
