Salvo,
If you're referring to the 4 amps used in the comparison, he does say it's roughly equivalent to a 60w panel. However, if I understand the point you're making; and if I understand how mppt works; the Imp used by mppt would be lower than the Isc used by pwm, and therefore, the power supply should have been adjusted accordingly, thus resulting in lower output wattage from the power supply, and therefore lower amperage out of the mppt.
