RL seems to have let these posts through (I haven't seem him "duck" an issue like this through comment moderation yet, if that's the bama-conspiracy-implication) - including one of mine w/links to EricsCC and LS - and he also responded with a cheerily optimistic truism that "it's not over til it's over". On balance, I think this is fair - the point isn't to harangue the writer for a "mistake" that a lot of people probably make (given the complication of figuring out even an *estimated* return) - the point is to provide information/clarification that may be helpful to everyone reading along at home.
*drama defused*
