Use the Benchmark
In shoe games it would lead too far to use different hilo-indices according to number of decks and penetration.As long as we use whole numbers there is anyway no difference.(My own attempt to introduce decimals got a rather heated reception here, some might remember :-)).
The only important specificatin you gave was DAS, since the splitting indices differ considerably from NDAS (even BS changes).
So, just use the multideck tables for DAS. They shouldn't be too hard to find on the net.
