Similarly, when used to express extent, “as far as” can indicate the scope or degree of something. For example: “She is as far as can be from being ready for the presentation.” In this case, it highlights the extent to which she is unprepared.

The subtle distinctions in using “as far as” lie in the clarity and specificity with which it defines limits or boundaries within a statement. Depending on the context, it can help provide a precise indication of the range, scope, or extent of a situation or concept.
