as far as i know the babolat machine measures ra-values as frame stiffness (but i might be wrong). i don't know anything about the pacific machines.

the dt-values with racquettune are to be taken with an appropriate grain of salt for the simple reason that they approximate some values for a generic kind of string. it is indeed very useful for relative tension loss but i would not take it as absolute data unless you go to the length og determining individual values for each string you measure - which is possible (but for me personally too much of a hassle).
