Sorry, thought you were talking about the note in the algo itself. Filed #226 to fix that issue.

Right, but the spec says nothing about that for now, so that's not relevant here.

> I don't understand you :) Sometimes you are worried about small things that do not affect performance,

You're mixing up implementation optimization, which is not the spec's business, with normative spec content which might force implementations or web developers to use patterns with known performance issues, which _is_ the spec business. In particular when that's been flagged by the TAG as an issue.

Again, please see:  https://w3c.github.io/sensors/#equivalent.

> Problem is that algorithm is in a wrong place and does not do what it should do, suspending sensor when data should not be provided.

Again, that's an implementation optimization.
