HVAC Design Training: Manual J Default Air Leakage Inputs vs. Blower Door Test ACH50

I'm pretty sure the awesome folks who created Manual J (like Hank Rutkowski- hear my interview with him here https://www.youtube.com/watch?v=ki8xKFyYZhc), and the softwares we use to run the calculations (Elite RHVAC, used here, and Wrightsoft) do not have a lot of personal experience with the test dynamics of home enclosures, and may never have actually used a blower door before.
Here's a demonstration of why it's so important to respect the blower door if you're doing HVAC design for residential construction or home improvement.
