That paper redefined what it meant to toss a coin making their concussion meaningless in practice. For a more in dept real world analysis.

PS: Of note they where detecting bias in the range of 1% that’s difficult to detect by hand.

You're presenting it like your article substantially rebuts the point. When the absolute best bias you can do is 1% above random that's pretty much "fair" as far as practical usage.

It's not even clear that's a real bias or just random noise, or an anomaly of their testing setup.
