=== Calibers ===
Calibers are a way of measuring the distance between CP and CG - it doesn't make sense to solely measure based on distance, as a 3'' difference on a 2'' OD, 24'' long rocket is very different from a 2'' difference on a 10' long, 6'' OD one.
Instead, calibers measure the length between CP and CG, divided by the outer diameter of the rocket, allowing for a much more fair comparison between different rocket sizes. For context, a CP of 1.5-2 is considered good, while numbers outside of that range tend to be either under-or-over-stable.
