老师第六题解析里的一段话：This creates a form of dollar cost averaging over time. The ladder has less reinvestment risk in any single year versus the barbell (or bullet). 然而按照课上老师讲的，“compared to barbell, the ladder portfolio has much less cash flow reinvestment risk.”对于Reinvestment risk的排序：应该是Barbell > Laddered > Bullet 对吗？那么这段话的解析has less reinvestment risk in any single year versus the barbell (or bullet)，Laddered再投资风险比 barbell (or bullet)都小，就不对了呀？
