After looking for a comprehensive chart on the game's stat scaling and not finding one, I decided to attempt one myself.

You can check the official BallsiticNG docs here for what the various stats do.
https://ballisticng-documentation.readthedocs.io/en/latest/unity_tools/custom_ships/ingame_prefab/physics_stats_setup.html

This guide will focus on relevant stats since many of them go unchanged between ships.

The format below is meant to display your desired front-end stat, followed by the recommended value range to be set in the stats in the editor.

(Note: Some ships have odd balancing which may reflect in the values below. Keep in mind high end ships such as the NX2000 and Barracuda models occupy the top level data sets, making for a larger range for maximized stat values.
If you intend for your ship to play in multiplayer, I advise keeping it fair and within recommended ranges.)

=== END ===

Here's the source spreadsheet I used to put together the ship stat values: https://docs.google.com/spreadsheets/d/1RRlHyi2nfg19sydwl6uqXWL-y1ohiXOo/edit?usp=sharing&ouid=102658826091725668260&rtpof=true&sd=true
I extracted what my patience allowed, which was the main line of ships accessible in the campaign.

Remember, it's still your ship, and this is not an official scale. I just wanted an easier way to setup some decently scaled stats without tediously pouring over charts and files.

Have fun going ballistic!
