Most enthusiast benchmark posts are unrepeatable six weeks later because the conditions were never written down. A minimum viable procedure:
- Fixed thermal start: idle at the desktop until package temperature is stable for two minutes.
- Fixed power state: AC, one named power plan, screen brightness fixed.
- Fixed background: same set of running applications, updates paused, no browser.
- Five runs minimum. Discard nothing. Report the median and the range.
- Record the Windows build every single time, because it will change under you.
The range matters more than most people think. If your five runs span more than the effect you are claiming, you have not measured the effect.
