-In [4] it is described that "With proper adjustment of these parameters, errors in distance traveled and angle of rotation can be held to 2% or perhaps less". See if this can be achieved.
+In the leJOS documentation it is described that "With proper adjustment of these parameters, errors in distance traveled and angle of rotation can be held to 2% or perhaps less". See if this can be achieved.
 
 Our values and test drives reveals an error of 1.8%, (50.8 cm / 50 cm * 100 )- 100 = 1.8 % error.
