Not random, just think of BB and SBB as separate, the 7% is a reduction in BB and when u hit SBB then it becomes 15% (It would also be more work for the game to put rng everytime u bb/sbb) i.e a unit needs 20 bc for BB, then SBB they would need 20 bc from BB and another 20 bc for the actual SBB so SBB is actually 40 bc to activate.
