1:1 movement is when the movement with your hand corresponds to that of the screen.
For example, if you have a mouse set at 400CPI and all other parameters are 1:1, every inch of your hand should travel 400 pixels on-screen.
All acceleration depends on the speed at which you move the mouse, the faster, the further it will travel from what 1:1 movement should accomplish. Saying that, there's two types of acceleration :
Positive acceleration is when the movement of your hand gets translated into a larger movement on the screen.
For example, if with 1:1 settings you make a fast turn of 1 inch, it will land 400 pixels on the side you've swept to. With positive acceleration, if you do it slow, it will get further from those 400 pixels, and if you swipe very hard, it might land very far from those 400 pixels.
Negative acceleration is when the movement of your hand gets translated into a lesser movement on the screen.
For example, if with 1:1 settings you make a fast turn of 3 inches, it will land 3x400 = 1200 pixels in whatever direction you've moved. With negative acceleration, if you make a slow swipe it might land a bit short of that number, but if you do it faster, it will get closer and closer to the original position of the cursor.
Inconsistent acceleration is when you have a mix of positive and negative acceleration at different speeds, such as what happens with A9500/S9500/A9800 sensors at the moment.
