I wish the results were reversed, so I could "well actually" your comment, but 'site:news.ycombinator.com "well actually"' gives ca. 4k results in Google and 'site:news.ycombinator.com "I think you'll find"' gives close to 17k results, so you appear to be right.

Well, "it turns out that" beats both, with about 26k results ;)

site:news.ycombinator.com "in my experience" 120K results

IANAL: unfortunately only 10.6k results, thought I had a winner for a second.

I am mildly disappointed that none of the phrase pitches in this thread were phrased with the given pitch.
