I've not used it, but anecdotally, I can refine my own search query to get what I want, or conclude it doesn't exist, within 20-30s. Assuming ~5s per search to write, search, read, decide, that's 4-6 searches.
Do you think you're getting more value than 4 iterations on the initial search term? Are you always getting it in one search, or do you end up still needing to refine the search term, extending it beyond that 20-30s?
