Thanks -- this is actually helpful. I want to be more cognizant of my writing style, I have a lot of room to get better. I often start sentences with "But" and use the same modifiers (However, Unfortunately, etc) quite a bit.

When I write I usually start with a big, unfiltered brain dump, then some formatting and then a proofread. But the proofread is in chunks of reading, fixing, reading etc so I never get the entire flow of it to catch these i-just-used-the-same-word-in-the-last-3-paragraphs issues.
