Btw this might sound trivial, but for people with a central ducted HVAC system it’s quite common for the central fan to pressurize/depressurize rooms with closed doors, which in some cases will be the largest driver of infiltration. So simply having an AC or furnace cycle on and off during the experiment would be quite bad for the results.
Good point! I’m used to houses with the older systems (steam, forced hot water) that are common in the Northeast and wasn’t thinking about this effect.
