Taylor,

"First it should be noted that both the Vanguard and the Alpine methods discussed are far superior to liquidating shares of mutual funds to eat..."

True.  Of course, if you were to withdraw anything more then 3% from VPGFX (the 3% distribution growth fund), you are doing just this (liquidating shares).  So, compare withdrawing 7% from both of the Vanguard funds to ADVDX!
