It gets closer to the total the more you multiple it, yes. However, the exact fraction is never specified. So, if a Artifical Sacred Gear's Counter-Balance is 1/10 of Balance Breaker, then yes, x10 Counter-Balance would be Balance Breaker. But that's only if it was 1/10, or 10%. If it was anything lower, it wouldn't be 100% if x10'd.
