Hello Everyone, since Obsiv is such a great guy and turned his head on many thing's I've done. I Figured I'd make a contribution to the community with a little mini tutorial on the how to get started with curve editing ill be linking a topic i used when i first started making curves. Enjoy.
The basics ==> http://xim4.com/community/index.php?topic=21648.0***I have my screenshot examples on hip...all these basics apply to both hip and ADS curves.***
1.Choose a Sensitivity to start at. Look to see when your xim blinks. This is when you've reached the "end of the curve" E.I. maximum stick throttle.

*note* Just because its a low number doesn't mean it will be slow. You can recreate this another way by editing your curve. example below. Many of my curves for ADS use 1.7 Sensitivity at 12,000 DPI.

*note again* since The x-axis is mouse velocity. When editing the curve later, if you have it 'peak' to maximum stick velocity half way thru. The rest of the 'mouse velocity' goes unused. and swiping faster will not go faster. To many, this is known as a 'slow feeling'..
2. Knowing what mouse velocity corresponds with what part of the curve. Get a "feel" for what mouse velocity effects what part of the graph. I do this by doing soo..

Once i go faster than that, my movement will suddenly stop. I find it a lot easier to edit on lower sensitivities since its a lot easier to predict when the stops are about to happen.
3. Screw 1:1. When editing your curves, find a good ratio you like. by ratio i mean, the amount your 'y-axis' increases when you move your 'x-axis' for example. below i have a curve that has 1:1 at the beginning which goes up by 5 evenly., in the following curve it starts going up by 10 about half way through. In this 'zone' many people feel a "snap" feeling. It's nothing more than sudden mouse velocity that got suddenly stopped with the help of AA. This is one way of optimizing AA.

4. Start from scratch..By doing this you don't have a frame your editing off of. create your perfect curve. if you like shooting from a distance go up by ratio of 3 for the first 20% of the curve. Then go up by a ratio of 7. or build up to that ratio by going up by 3.5...4.5...5.5.. play with it. I start this process by doing so...start from nothing and feel your curve every step of the way.

The biggest advice i can give is, play with it. If you find its 'too much, you can always go back to 1:1. This is for those that truly want to customize their aim to best fit their play style. This is also a tool you can use to exploit certain in game mechanics more efficiently. I.E. AA.
This is my contribution to try and help people until a more proper and formal editing tutorial is made.
Only reason i took MY time to make this is because of all the people who have supported me. Some of you are beyond generous! :')
Your move haters..
