Please feel free to conduct your own experiments. I’ve now done three, with three different streamers, with similar results. The experiment is so simple, it’s a bit of a puzzle as to why you resist, other than it allows you to keep the "argument" alive.
Of course, you’re also free to copy/paste here, rely on press releases and the like. Suit yourself.
