The table below depicts why higher savings rate people don't feel it early on (or low SR people for that matter). Assumes you put in $50k each period and a 4% return (real) and demonstrates the WR at each period assuming $40k spending. Early on the absolute returns are small but the increases in portfolio are great and the decline is WR is great.
As it gets much later in the periods the returns are >/= contributions and WR doesn't change much period to period - also demonstrates that OMY doesn't really help all that much.
