Don't jump to conclusions...  Transverse sensitivity is also determeined by the
construction of the accelerometer package.  Each package design 
(crystal+inertial mass+envelope) must be evaluated.  Experimental shaker data 
is the only reliable measure.  Admittedly they are usually pretty good, but 
do look for manufacturer's test data..
