I find that editing dimensions is very very easy.
For the record, as far as tolerance/precision/etc... NEVER edit, aside from adding text notes to the end... such as "MIN" "MAX" and sometimes if I'm doing control joint spacings on a large foundation slab, I'll dimension an overall and edit the text to be "18 JOINTS @ 25'-0" O.C. = 425'-0"" with the 425'-0" being an unedited <> dimension.
Otherwise it's dimension style for everything. You can't exactly automate something for notes.
