CALCULATION OF TOTAL PARALLEL CAPACITANCE. The formula below calculates total capacitance of a group of parallel connected capacitors. When entering the size of the capacitors, the units must be kept the same from one capacitor to the next. For example, if Capacitor-1 is entered in micro-farads, Capacitor-2 must be entered in micro-farads.

If it said, "2x Panasonic 470uF model XYZ", or "1000uF with < 0.1 ohm ESR" then that would be somewhat rational. But otherwise, surely there''s a wide range of performance characteristics for both 470uF and 1000uF capacitors -- there must be 1000uF capacitors out there with a way better ESR than 2x some marginal 470uF capacitors.
