Not really, of course. But here's my story:
I moved into a 1350sf ranch home (3/4 basement and 1/4 crawl) in Columbus, OH last year and have been working to air-seal and insulate it. I ran a blower door test before I began just to be nerdy and track my progress. Initial leakage was 3075cfm @ 50 Pa, about 9.7 ach50. I started work in the attic, sealing up everything I could find before blowing in cellulose over my skimpy loose fiberglass.
