I feel like the explanations would be much easier if it looked like code.
Example:
If the d20 ≤ STAT it’s a Precise Hit: …
Else, if the d20 ≤ SKILL it’s a Good Hit: …
Else, if the d20 ≤ SKILL + SALVAGE it’s a Messy Hit: …
Else, it’s a Trouble: …
feel free to hack it or make an add on in that format. I’m hoping to get back to this with a little graphic visualization.
