Definitely.
The OS turns the display on/off based on sensors readings and there's generally a range of values from an off state to a max value, so they can tweak the tolerance point.
For example, the accelerometer might read from 0.000 to 1.000 and it's at something like 0.400 that triggers true, they could move that down to 0.350 so that it requires less speed. 😎
Since all that's easily adjusted on the fly, I wouldn't mind some user defined parameters so I could fine tune it to my particular movement angle/speed, etc.
