Don, would you suggest to round down deck estimation in single deck?

[Dog Hand]

San Jose Bella,

If you combine your quoted text with the next paragraph from your picture, you can see that Don is rounding to the nearest quarter deck: 8 cards used counts as ¼ deck gone, so the TC denominator is ¾, while only 6 cards used counts as 0 decks gone, so the TC denominator stays at 1.

Hope this helps!
