According, to the user tab on Skeptics, both Fabian and I have edited over 80 posts. By that logic, both he and I should have our Strunk & White badge, but it's missing for us both.
Ivo Flipse is also missing the badge on Fitness & Nutrition.
The users page tab for editors lists all edits, including edits to your own posts and retags. Strunk & White only cares about body and title edits to other users' posts.
Unless you avoid all forms of editing that do not qualify for Strunk & White, that page will not accurately measure your progress towards the badge. I'll quote the Badge requirements list for your convenience:
- Edits to your own posts do not count
- Edits to CW posts do count
- Edits that consist only of tag changes do not count
- Tag wiki edits do count
- Edits you suggest before gaining full edit privileges do count, once approved
See my answer to How do I know how many posts I've edited? for the best way to see your accurate edits. That users tab seems to show all edits - even to your own posts (mine says 244 on Programmers, while the query says 84, which is correct — I just earned my Strunk & White badge).
