I both agree and disagree. I imagine most people could tell the difference between an 8th year and 3rd year sushi chef. 3 years seems like such a short amount of time for something as complex as making sushi. On the other hand, I also can see that when people reach a very high level of skill, it may be difficult for normal people to really see the differences in skill. But I don't know if you can really say there's only a marginal difference. After all, if one person is 10000 miles away and another is 11000 miles away, they both are so far away you can barely see them. Indeed, I imagine they may be so far away you can't tell how far apart they are, or even which one is farther! But the reality is that one of them is 10% farther than the other: hardly a marginal difference. Still I do agree that non connoisseurs probably would have difficulty truly appreciating the difference in skill.
