so, after you measure this, what are you going to do?
why not just do that? work on the solution, not just measuring how much problem --
eg: seal all the ducts & cracks with mastic
have dampers in the duct take-offs from the trunks
adjust dampers until all rooms are +/- 3F just after blower shuts down
it takes some patience to set dampers --
& may need different settings for summer & winter
