Aggregate score
-0.58
Dataset-relative weighted score from CPI bias, CPI jitter, and CPI drift. Jitter and drift receive extra weight. Higher is better.
Mouse benchmark record
A4Tech / Bloody Bloody V5 CPI Benchmark

Record date: 2026-05-30. Interactive record: open this mouse in the benchmark app.
Recommended mouse pad for A4Tech / Bloody Bloody V5: SOFT pad. Best measured setup: 800 CPI on SOFT pad.
Research basis
Built on Peer-Reviewed Mouse and Pointing Research
temppal.gg is not a review blog. It is a measurement site from YESLAB researchers whose prior work covers mouse sensing, pointing models, gain functions, button mechanics, aim-and-shoot behavior, and esports input performance. These papers explain why CPI fidelity, jitter, drift, and player-side tests are scientific measurement problems.

How to read this result
CPI bias is computed from the fitted base CPI parameter c0, not from a single raw measurement. CPI jitter is the residual variation after the fitted model accounts for motion, and CPI drift summarizes how effective CPI changes with translational speed and angular speed over the tested motion range.
