I have always had a hard time equating ROI on any windfall probability. I view lottery systems as a windfall system in that the chance of winning is zero and the expense of playing is trivial, so any investment has no expectation of return it only allows for the possibility of windfall. The $1600 investment over 30 years would not have noticeably increased or decreased my QoL so it is not a lose in my mind, only a technicality.
