FWIW, I have the same problem on my new 2015 Legacy (with the CVT). I estimate the accel. travel to move the car from stop to highway speeds is about 1/4". In other words, the slightest touch of the accelerator lurches the car ahead. I have to think throttle response (how far you have to press the accel. down) is fairly standardized in the industry (Prius and some hybrids excepted). With that, I can't imagine why Subaru designed an accelerator that is so insanely sensitive to the slightest touch. 'Course, for that matter, I don't know why the Legacy CVT "shifts" or causes engine deceleration in the lower "range". Cruising around 1,000 rpm, trying to maintain a gentle, steady speed, my CVT hunts from low to the next highest "range" and there is some accel. and decel as it "shifts". When the CVT decelerates the car it is very easy to overcompensate when pressing on the accelerator. This results in what could be described as "drive train slop" or "surging". I won't be keeping this car long. Too bad, because other than the throttle and CVT it is the perfect car for me (styling, comfort, etc.).
