Up to thirty runs per drill are kept on this device.
How to pick a drill, and the sensitivity mathSensitivity converter
Compare two setups by the distance your mouse travels for a full 360 degree turn.
cm/360 = 360 / (DPI x sens x yaw) x 2.54
Current setup
Target setup
- cm/360
- 1.14
- inch/360
- 0.45
- Matching sensitivity
- 0.5000
If you do not know the yaw, set both sides to 1. You then compare DPI and sensitivity only.
Worked examples
These five rows are the formula above, computed as written.
| DPI | In-game sensitivity | Yaw (degrees per count) | cm/360 |
|---|---|---|---|
| 800 | 1 | 0.022 | 51.95 |
| 400 | 2 | 0.022 | 51.95 |
| 1600 | 0.5 | 0.022 | 51.95 |
| 800 | 2 | 1 | 0.57 |
| 1000 | 1 | 0.05 | 18.29 |
Where we looked for yaw values
No per game yaw values are shipped, because no official document we opened publishes one.
