Here is a common enough scenario that shoots the full power, clean it up and go around every-time-as-per-SOP theory down. Suppose you have a circling minima of 500 ft. You have arrived off the NDB approach (or whatever) with minimum legal fuel and get visual at 500 ft - maybe a bit higher - but the cloud is most certainly solid overcast at 550 to 600 ft. Now at 300 or 400 ft on final some mug taxies onto the runway, forcing you to go-around, or maybe you just screw it up and get too high, or too far off centerline. Are you going to instinctively go into the full missed approach scenario and climb back into cloud? Bad, bad choice. Ease the power up to what is needed (probably no more than climb power on most twins due to the inertia and small height gain required), return the flaps and gear to circling configuration for the particular airplane type, and level off at 500 ft for another go.
Once you go back into that cloud you have no choice but to conduct another instrument approach with less than minimum reserves. THAT my friends is poor airmanship, and in the past has resulted in more than one pilot failing a checkride.
Now, I await the holier than thou's who would never find themselves in such a situation.
