Fundamental does not mean "complete". It is the beginning of the idea. Cutting Mr. 1 was certainly an achievement, but Zoro cannot cut just anything. Indeed, we have seen him fail.And I'm not thinking in as concrete manner as you are. When fighting against Mr. 1 Zoro was thinking back to the old lesson of being able to cut nothing. It was a fundamental part of being able to cut everything, not to cut steel. Or let's say to understand any material and thus be able to cut it. Steel as such has got nothing to do with it. It was just one important step, because normally you aren't able to cut steel. Maybe he would need to learn also to cut Pacifista's material, but that shouldn't be so hard anymore for him, after having already learned the fundamental lesson.
Remember, Mihawk's sword was the one famous for being able to cut anything, and Zoro is working to surpass him. It's not so surprising Zoro is weaker half way through the Grand Line. Rayleigh is supposedly 100 times stronger than Luffy...
