If you don't get an answer, you can also figure this out by hand with information and concepts from BRH's
http://www.bjmath.com/bjmath/counting/unbalbal.htm and also, the work done for you Color of Blackjack KO supplement if that's the unbalanced count you use.
Take an IRC equal to your -(unbalance*starting decks). Your starting true count will simply be set equal to -(unbalance). So, for KO and a 6 deck shoe, you have an IRC of -24 and a starting TC of -4. Your starting TC will always be the same, regardless of shoes. KO's would always be -4, Red 7's would always be -2.
Now, you simply divide your running count by decks remaining, as you would a normal TC conversion, and round down. So let's say at 5 decks, you have an RC of -17. Divide and round down -- you have a TC of -4 still. Let's say at 5 decks you have an RC of -15 -- you now have a TC of -3. Your TC has increased by one, and that is roughly the equivalent of moving up one TC in HiLo.
When you find the RC per deck that your TC first increases one, there will be at least an indication to the answer to your question, depending on the rules you're playing against. The magnitude of the difference between your IRC and the RC where you see the increase is the number you can take and add to whatever ACTUAL IRC you want to use. In the example above, it was 9 (24-15). If you want to use an IRC of 0, you could simply know that at 5 decks, you have an advantage at RC 9 (well, you have the rough advantage equivalent in HiLo TC+1, whatever that might be for your game.)
Lastly, so for KO vs the 6 deck shoe, your numbers will work out to be 9, 12, 15, 18, 21, for 5 decks, 4 decks, 3, 2, 1 decks, respectively. And of course, a change in RC = +24, the pivot in this example, will ALWAYS be equal TC of +4, regardless of decks (0 divided by any decks is always equal to 0.)
My apologies if you already knew this and your question was specifically related to the software and the software alone...
