Not a big issue in any way, but if you're using a numeric parameter value 
anyway, could not one use a range of the permissable values to set a seed 
for the random generation, so that the test can be repeated with the same 
set of random numbers?

Something like

0 => 55/AA
-1 => random
1 and up => random, specifying seed for random number generator.

I'd suggest something like "0 for 55/AA pattern (default), non-zero for 
random pattern".

(Or "-1 for 55/AA pattern (default), else random; >=1 sets seed" if 
changed according to the above).
