From reading multiple of his posts on the subject I believe that this is the exact point he's trying to make by telling people to "never adjust the idle by a given gap distance but only by what the engine is telling you". Some people are interpreting JQs video in a way that tells them THIS EXACT idle gap MUST WORK and to NEVER touch it again, and if it doesn't they're doing it wrong, which simply isn't the case for all engines. Picking a small-ish idle gap to begin with as a starting point is not bad, but learning how to find the right idle gap is better, because it transfers across multiple engine makes and models at all different, altitudes temperatures and humidities.
