I guess I'm indirectly asking if the box reads a .2 atty and knows it has to exert 4.2 volts to hit 88 watts if that's what you set it at, will it actually hit less than 88 watts because of voltage drop, or does it read the voltage drop and exert more in order to get 4.2 volts to the coil? Know what I mean? Think about it.....
