You are certainly entitled to your opinion, and a DCC Master of the Table is a great achievement, a testament to all around excellence. That said, probably 98% of the world's one pocket players are American and 99.5% of the world's bank pool players are American, so what's the point of comparison.
It's also worth noting that the elite aren't always present at the Derby. For example, none of these players were at the 2020 Derby city Classic:
JL Chang, Kevin Chang, Anton Raga, Xiaohuai Zheng, Carlo Biado, Wu Jiaqing, Ko Pin Yi, Ko Ping Chung, Albin Ouschan, Niels Feijen, Francisco Sanchez Ruiz. Klenti Kaci, and Fedor Gorst.
That's thirteen of the world's twenty best based on Fargo. Let's not try to confuse the kind of fields you get at the Derby to those found at majors like the US Open, China Open, All Japan and the World Championship. The Derby is great, but it's not quite a gathering of all the elite.
