No... and yes
The short answer to your question is no.. BUT
I've looked quite a bit into this. The UBZII indices, as you know, are pretty well set in stone for multi-deck, but I wasn't happy with this so I did a bit (actually a lot) of experimenting.
I prefer to handle unbalanced counts by keeping the KC constant (at 1 for example) and moving the IRC and Pivot points depending on the number of decks. This way I can start betting up at KC and higher without having to adjust my thinking too much when it comes to betting.
I ran some sims using Blackjack Statistical Analyser and CVData for different deck sizes and found that using the KO principle of a rounded set of indices, I was able to adapt it to UBZII with favourable results. It's not absolutely perfect, but this adaptation works for any number of decks, and that's why I use it over KO.
With 4 deck, for example, I set IRC at -10, KC at 1 and Pivot at 10.
I also have figures for other deck sizes, but I don't have them on me at the moment. (I usually play 4 deck.)
Please don't ask me to explain the theory of it or anything like that. And I know it's a bit of a fudge, but I also know that I am getting superior sim results to the original UBZII multideck figures (and KO), and it's a lot easier and quicker to use because I play it like KO. Once you know KO it's a piece of cake (that is once you can count level 2).
Hope this helps.
