Default T/S parameters for drivers in parallel

Hi all,
does anyone ever measured the T/S parameters for a set of drivers in parallel ?
Are the rules of thumb (usually stated: Re:=Re/N, Vas:=n*Vas, ..., and so on) confirmed by some measurement ?
Thanks

For modeling two drivers wired in parallel Vas, and Sd are doubled, impedance in halved, and SPL is +6.

I posted this in a previous thread:
-------------
Assuming that

a is the number of elements that are connected in series, electrically,
b is 1 for normal configuration 2 for isobaric configuration and
n is the total number of elements,

Vas1=Vas*n/(b^2)
Bl1=Bl*a
Sd1=Sd*n/b
Re1=Re*a^2/n
Le1=Le*a^2/n

Isobarik mounting meaning mounted in pairs, no more. Index 1 are the new values.

-----------
For two elements connected in parallel electrically and mounted side by side on the baffle (not isobarik), a=1, b=1 and n=2.
