Wouldn’t excellence be a habit only if one frequently and repeatedly performed at “superior” levels?

And since doing anything excellently usually takes practice and improvement from satisfactory to mediocre to good, Aristotle must also have believed that these less than excellent levels were also habits.

If that is true, then wouldn’t it also be accurate to say that, in most cases, excellence is not just a habit, but also a product of determination or the resolve to perform excellently?
