Edit: Looking for better file hosting options if you have any suggestions. Ideally if someone could host this so it doesn't need to be downloaded.Ballistic Curve Creation Tool 2.01Update 2.01: Added "LA" slider, thank you Lemon1 for the idea. Also made the two buttons larger, as they were a bit small for me on mobile.
An entire year later, I am back with a completely rewritten and revamped ballistics curve creation tool. This version has sliders, live visual updates, and can be locally hosted on your computer or even phone so you can easily paste curves into Xim Manager.

The tool can be downloaded
here.
Please experiment, share curves you like here, and enjoy easy creation with a more user friendly tool than the old spreadsheet. I'll answer some common questions below, and probably continue to add to this list as more users have questions.
What is B?B is my own version of Boost, which you should be familiar with from the advanced feature options on newer Apex firmware, or from Xim4. Boost allows your initial motion speeds to be higher, which can help you cut out of aim assist and snap from target to target.
What is SA?SA is my own version of Steady Aim. Steady Aim limits your aim speed to specific discrete values. This helps you cut through the aim assist "bubble" and get on target faster.
How does SA cut through aim assist?When you are approaching a target, your natural instinct is to slow down your movement as you get close. The problem is that when games have aim assist, they have this slow down built in. Your own instinct and the games aim assist compound to form this "bubble" that prevents you from getting on target. Using Steady Aim can help your Xim ignore your instinct by not slowing down the rotation when you slow down your mouse (as you stay on one of the "steps" of the curve), helping you get on target faster.
What is SAD?SAD is Steady Aim Distribution. This value decides how the discrete "bins" are created, allowing their density to be higher or lower for higher or lower sensitivities.
What is F?F is Fuzz. This setting can have a similar effect to SA, but it does not discretize your sensitivity and instead causes it to oscillate between fast and slow settings. If you've ever seen someone shake their aim back and forth on a target, the goal is this is to naturally give this affect of lurching aim to help cut through aim assist quickly, but it may have adverse effects on the smoothness of your aim.
What is LA?LA is Linear After. Place the slider at the point you'd like the custom curve to end, and continue as the same good old fashioned linear curve at the same sensitivity you're used to. Great to have a curve for cutting through aim assist, but keeping similar response for those fast flicks you've been training for for your entire existence.
What are X, Y, and Z?These are parameters that control the shape of the overall curve, and affect each mode differently. Certain modes may not be affected by all of the sliders, for example Power is only controlled with the X value and is unaffected by Y and Z.
How do I use a curve?Click "Generate Xim Ballistics" and you should see your curve in the textbox. Select "Copy To Clipboard" and it should now be in your devices clipboard. Open up Xim Manager and paste it into the ballistics editor and you should now see the curve and be able to use it on your Xim Apex.
Have you ever though of making a curve do X?No, but I definitely can add that feature for users to experiment with. I'm open to all suggestions in terms of added functionality and modes.
Give curve for X game.I'm open to discussion on what features are useful for certain games, and sharing curves that you have created and are useful here, but
this is not a place to request curves, it is a place for sharing them.
To Moderators: Please unsticky my previous curve creation tool and replace it with this thread. I am very tired of the incessant emails requesting for access.
