Small battery gains on macOS 14.3

After updating last night, my M1 Air jumped from about 7:40 to about 8:10 screen-on time under the same 3‑app workflow (Chrome 121, Slack, Zoom) at 200 nits, Wi‑Fi on. Anyone have repeatable battery tests or a benchmark script to confirm whether this 6–7% bump is real vs noise?
