It is true that an approach flown at correct speed and glide path and good directional control during flare and landing resulting in touch down in the touch down zone qualifies as good percentage landing. Any one can do a greaser by floating beyond the touch down parameters but it only gets negative marks. However it is perfectly possible to do consistently smooth landings within touch down parameters but that requires seat of the pant feel and I am not sure it can be acquired. You will see some people routinely do it yet with some others it is a matter of chance. Those who fall in the later category can be extremely good pilots otherwise.
