KO- When to play multiple hands?

I use the KO Preferred System and was wondering at what RUNNING COUNT should the counter spread to multiple hands for the 6 and 8 deck game? Certainly at some count it must become profitable for the counter to spread to two hands. Perhaps it would be at the Key Count or Pivot Point?

For some reason this topic is not discussed in Knock-Out Blackjack. I have not seen a post on any BJ Board which discusses this matter either. Does using an unbalanced counting system mean you should never spread to several hands? Thanks to anybody who can help on this one.
