- No, V is second order variance (average of the squares of deviations)
- Have you read the Trice? It's a bit hard to explain, and my path to confirming Sam's 33/7 included some handwaving (as the article does, but in my case the handwaving is due to lack of understanding, in Trice's probably not). Here's a bit from the article that might help: In a very long, one sided N-Roll bearoff, what's the probability that your last checker is born off with a roll of doubles?
SPOILER
(It's 2/7, and Zare's elegant explanation which is quoted in the article is that that's due to the fact that ~2/7 of ALL checkers tend to be born off by doubles.)
