I suppose that it is perspective. If I play, for example, Scotland The Brave and I miss a not, I play it again with the expectation that this time I will not miss the note. Since missing the note the first time was not intentional, I really am doing the exact same thing and hoping for a different outcome - fewer missed notes. Well leave tuning and tempo out of it for now. Basically, to practice, I play slowly, in the hopes the my fingers will remember the repitiion (muscle memory) and hope that eventually the outcome is that I can play without effort.
I see not missing the note as a different outcome, not doing something differently.
