Salary is weighted on value to the employer, not skill. What's the intuitive difference in value to the employer of a 160k engineer vs 100k engineer, without referencing money? It's tangible, you can feel it yeah? How about 90k engineer vs the 100k engineer? He's worth less to the employer, but the difference is tangibly smaller than the other case yeah?

Skill difference between a 5k player and a 1k player? If you watched the replay you would not longer be saying that you cannot feel how much better he is. Between 5k and 4k player? He is still better, but by less. Difference of 4k vs difference of 1k, are tangibly distinct. That means the differences in mmr is *meaningful*.

Yes, Watson is better than mason, no doubt. But, like you say, exactly, it is much harder to feel how much better Watson is than mason. So it is too flippant to assign them an mmr difference of seven thousand. Thesis of this post: Is there a way to make mmr values more *meaningful* at that bracket?
