Shooting Accuracy is a Stat: Base chance to not miss per square of shot distance.
Factors
- Shooting skill
- Sight: 12x importance—capped at 200% efficiency here.
- Manipulation: 8x importance—capped at 100% efficiency here
- Traits
- Trigger Happy: -5.0
- Careful Shooter: +5.0
- Post-processing curve
The Gunlink 
also provides a buff.
It is capped at 99.9% per tile, though 99.8% seems to be the highest achievable value in vanilla.
- +20 from 20 Shooting skill
- +12 from 200% Sight
- +0 from 100%Manipulation
- +5 from Careful Shooter
- +3 from Gunlink
This results in a sum of 40, which the post-processing curve translates into a 99.8% value.
Analysis
The table below shows post-processed shooting accuracy per tile of distance for each skill level and trait combination, assuming the pawn is healthy:
| Skill Level | Standard | Careful Shooter | Trigger-Happy | Skill Level | Standard | Careful Shooter | Trigger-Happy |
|---|---|---|---|---|---|---|---|
| 0 | 89% | 94.5% | 84% | - | - | - | - |
| 1 | 91% | 95% | 85% | 11 | 97.25% | 98.333% | 95% |
| 2 | 93% | 95.5% | 86% | 12 | 97.5% | 98.5% | 95.5% |
| 3 | 93.5% | 96% | 87% | 13 | 97.75% | 98.666% | 96% |
| 4 | 94% | 96.5% | 88% | 14 | 98% | 98.833% | 96.5% |
| 5 | 94.5% | 97% | 89% | 15 | 98.167% | 99% | 97% |
| 6 | 95% | 97.25% | 91% | 16 | 98.333% | 99.125% | 97.25% |
| 7 | 95.5% | 97.5% | 93% | 17 | 98.5% | 99.25% | 97.5% |
| 8 | 96% | 97.75% | 93.5% | 18 | 98.666% | 99.313% | 97.75% |
| 9 | 96.5% | 98% | 94% | 19 | 98.833% | 99.375% | 98% |
| 10 | 97% | 98.167% | 94.5% | 20 | 99% | 99.438% | 98.167% |
Note that shooting accuracy for the pawn has exponential decay calculated per tile, meaning that a small increase (even 1%) in shooting accuracy will have a significant effect at longer ranges.
For example:
- A colonist with shooting accuracy of 99% has a base accuracy of 72.5% against a target 32 tiles away (0.9932 = 0.7249)
- With 98% accuracy, the base accuracy against the same target becomes only 52.4% (0.9832 = 0.5239).
