Can we have a unidirectional constraint implementation

In reply to dave_59:

Thanks Dave! I got what you are saying.

To be more clear, if the weights are such that

Weightage :

cmd               size 
------------------------------
cmd_B =90%      size_64 == 10%
cmd_A =10%      size_others = 90%

The combinations can be

{cmd_B, size_64} <= 10% of total weight,

But also, since the cmd_A is only chosen 10% of the time,

{cmd_A, size_64/size_others} ~= 10% of total weight.

Therefore, does this mean the above combination of legal values will happen almost in equal numbers . i.e 50% of the total number of legal combinations.
