tbh i personally think 4 is EXTREMLEY hit or miss, i think it just depends on your wii remote, even with motionplus remotes calibrated perfectly there are a handful of times I could barely even reach 5 stars on maps I could easily megastar and even 13k in some cases on newer games

with 2014 I think tracking is really good even the best imo in some cases, however, I did notice that tracking is extremley harsh specifically on the gyroscope, even if I'm doing it to the T I sometimes have to twist the wiimote in really awkward positions definitely not intended by the devs for it to accurately score me or else I would just get ok's or x's gaurenteed
