Figured I'd start a thread for this, now that more people are using the Edge and are probably going to want to experiment with the ballistics curves. The user manual covers common types of curves for the Edge, but they will still require some tweaking to feel right.
*NOTE - for any of the curves below, you should adjust your sensitivity to your play style. I'm running a 3000dpi mouse, so if you run 5700dpi, you will probably have to lower the sensitivity.
BASICSwhen you open up the ballistics screen, you'll see two graphs - one for hip fire, and one for Aim Down Sight (ADS). Each graph will have a 45 degree line going from the bottom left to the top right. The bottom left starting coordinates are 0,0. I'm not exactly sure what actual maximum values are, but for sake of example, we will call the top right of the graph 100,100, which represents maximum turn speed at maximum mouse speed.
The ballistics curve starts out on top of the white 45 degree line. this white line represents the Smart Translator, and linear 1:1 mouse movement. Any point moved above the line will result in faster movement than that point on the smart translator, and any point moved lower than the line will be slower than that point on the smart translator.
So if you shift the top half of the dots above the line, you are creating a profile that is faster than the ST at higher mouse speeds. you can adjust the shape of the dots to create acceleration curves or even slow down parts of the movement range.
The general rule of thumb is anything parallel to the white line is linear (1:1) movement. if you shift the whole line up, it's like raising your sensitivity. Shift the line down, and it's like lowering the sensitivity. as long as it's a 45 degree slope, you will have linear 1:1 movement.
BOOSTThe original concept for boost was to emulate a config with a large deadzone on the XIM2, where slower mouse movements produced quicker look speeds, but while still retaining a mostly linear (1:1) ratio. It allowed you to skip the lower range of look speed, which produced a "snappy" feel, and would also make it easier to break free of the sticky-aim present in Call of Duty games while you were in ADS
Unfortunately, the current boost offset on the XIM3 caused mouse jitter at higher settings, so it's use is limited. I believe it was Roads(?) and some others that able to achieve good results using the peripheral bridge by making a mouse curve that ramped up speed quickly, but maintained a 0,0 origin in order to eliminate jitter.
So I came up with the curves below which seem to work very well. The idea here is to leave your starting point at 0,0 so you don't get jitter. Then you raise the rest of the curve equally to retain your 1:1 ratio for movement. Keeping the new curve parallel to the ST line will keep the rest of the movement range linear and 1:1.

Here is the curve data you can paste into the XIM Edge.

FINE AIMING CONTROLMaybe you like high sense all around, but need more control for slow mouse movements, like for sniping? Here is an ADS curve I tried that is slow and precise at low mouse speeds, but is faster at normal and higher speeds. This curve will let you use a higher sensitivity, but still have slow low-speed precision.
