I spent far too much time doing this type of testing on the annular booster setup I made for AVS carbs.
http://www.nzmoparforum.co.nz/index.php?topic=7933.0 it did work but I can sum it all up for you in about 2 lines
Carb flow & jet signal are a balancing act & more often than not if you change one you will compromise the other.
eg, tidying up your booster leg or venturi for better flow lowers the signal to the jet while increasing the signal to the jet with annular or skirted boosters will decrease the flow of the carb.
