That is a software induced feature of the wii, and doesnt actually have anything to do with the wii remote. The actual wii remote IR updates ridiculously fast far faster than your television refreshes, or any normal optical device like a camera, kinect, or the playstation eye.
To put it in perspective, playstation eye and kinect refresh at 60-120 hz. Standard to quite good for a high resolution camera. (although this is just the camera, a lag time of interpereting what is going on in the image is still applied on top of this) The wii u ir camera runs at 24 Mhz, which is 2,400 hz. (a computational lag time is also placed on top of this, but its so much faster than rendering a 480-720+ image that its completely inconsequential in the big picture, simple, elegent, effecient and fast. The wii remote was a fantastic design, something the wii u tablet shares)
It updates so fast that early wii games had problems with it being WAAAAYYYY to sensitive, to the point of responding to the pulse of the user holding it, and in general being a shaky mess.
So a software algorythm was used to average out and slow down the on screen output of the wii remotes ir tracking, to weed out those unconcious muscle movements, twitches, pulse, and other factore us squishy meatbags dont intend to actually have the system pick up, which, has many variations, but often results in the 'dragging the cursor' effect you were describing.
The wii u uses the same exact wii remotes as the wii, so sadly, they feature no improvements, which is a real shame, because as is, the broadcom inside the wii remote is unable to allow the wii remote to report at its full capacity, and in fact, the wii remote is forced to cripple itself, to cut down the amount of data it can record, to the amount it can effectively transmit to the system in a timely manner.
A true shame, by simply replacing that old broadcom with one that has just a little more bandwidth, the motion tracking of the wii remote would improve by orders of magnitude.
