When did I call him the "epitome of inconsistency"? Just saying he's not consistent--like most of the field. I'll have to recheck the results, but at this point in his career, Artur was actually more consistent (at least more successful) than Kovtun. Of course, Artur went and imploded since then, just to show how we can't use one season (let alone one performance) as a benchmark.
Agree with the second paragraph, but frankly the men have always been inconsistent. The result of greater jumping ability + wonkier balance, perhaps? The main difference right now is before, at least the top 1 to 3 guys were consistent, while now even the top two (Chan and Hanyu) aren't. I'd put Hanyu's chances of developing consistency far higher than Kovtun's though (and his mistakes cost less due to how COP works).
