You were the one posting the chart as gospel in relation to a not HED rim with a not HED tyre. Therefore you are the one making the clam. There is an inherent claim in your posts, that doing so is fundamentally different because you run a rim that is a few mm wider and that doing so is "better". Better how?

You cant keep answering these questions with claims that it is all self evident and "you have no experience". Thats not answer. Its just a cop out and a distraction.
