The baseline for this test seems to be an "open wheel." I seriously doubt that the improvement would be anywhere near that great if the Insight wheel were used as a reference. It is by no means "open."
Still, I like the moons and will give them a try. Already drilled and threaded my "worst" set of Insight wheels  |
Somewhere,I have a case study which summarizes the minutia of Shinoda's tests on the Firebird.I'll find it asap and report back.There were some other wheel configurations tested and you are very correct to think that the MOONs won't 'show' on the Insight like they might for the open wheel.
