Here you go....
If you still have Peter Griffin's book available, go to page 128, and then to the previous page, p.127. He lists the EOR's on page 128, but on pg.127 he does mention these EOR's are for single deck.
Both of these are basic strategy expectations. IMO, the effects of removal for 6-deck would be extremely close to those values.
Or, as we used to say, "close enough for rock-n-roll"!
Wong's Halves or Uston's SS count (unbalanced) are VERY close to optimal counts for that game.
