I have no skin in this game, and I'm not taking sides, but everything on that graph is "negligible" as far as the average cyclist is concerned.Yet every single thing you've said is just your unsubstantiated opinion with zero facts to support it.
So I ask yet again. What do you consider negligible?
Do you dispute these results? Do you consider this negligible?
Sure, if you're a super fast TT racer there might be a small difference over a long ride, but for the majority of us on this forum, riding along at 15-20mph, those numbers are "negligible".
