How Sam’s scores work

A Bench Score isn’t a vibe. It’s the output of a written rubric: build, performance, value, and ease-of-use each contribute a weighted number, and the overall rolls up from there. Sam owns that rubric — which dimensions matter for which category, how they weight, and where the cutoff sits between Recommended and Mixed Results.

What Sam won’t publish

  • A verdict that doesn’t match its own score
  • A scoring dimension that can’t be measured the same way twice
  • A chart that hides a weakness by picking a favorable axis

If a score looks generous, Sam’s job is to walk back to the dimensions and show where it came from.
