Perfect Pairs

I see the wizard has the math for Perfect pairs on his main website, I am interested in the exact same qualifying hands for 6 or 4 decks, anyone got the method to calculate this?

The numbers are under pay table D.

The method of working it out is fairly easy. Assume your first card in an Ace. You now have one of the 4*(number of decks) Aces, so there is one less for you as your second card. For instance with 6 decks there were 24 Aces, now there are only 23 left of 311 cards. 5 of these are perfect, 6 are coloured, and 12 mixed. Use similar logic for other numbers of decks (when the chances of a pair are better the more decks you have).

You can see that the odds used in casinos should be different for varying numbers of decks used.

There is a bet in Grosvenor [UK] casinos that allows for a bonus of 5 units if you also make Trips (using the Dealer's upcard), Typically they use 6 decks in CSM and 4 decks in shoes.
