Does CSS_NO_INLINE_FONT_SIZE_TINY affect my score?

Yes. It is an importance 6 rule at RESEARCH confidence, so a failure costs 6 × 0.7 points of impact in the CSS category before that category is normalised to 100.

What does RESEARCH confidence mean?

Backed by large-sample study or industry research, not a specification. Confidence is a declared tier rather than a per-rule number, so every rule backed by the same class of evidence carries the same weight - which is what makes the score reproducible instead of hand-tuned.

How this rule is weighted

Importance: 6 / 10; How much this matters relative to other rules.
Confidence: RESEARCH; Backed by large-sample study or industry research, not a specification.
Severity: error; How the finding is presented when it fails.
Scoring: Counts; A failure costs points in its category.

Impact is importance multiplied by the confidence tier’s weight — SPECIFICATION 1.0, RESEARCH 0.7, EMERGING 0.3, EXPERIMENTAL 0.1. Two rules backed by the same class of evidence therefore always carry the same weight, which is what makes the score reproducible rather than hand-tuned.
