SCORE Adjustments When Playing More Than 1 Spot

[BOND]

Today I was reading "Blackjack Attack" (3rd Edition) and how SCORE needs to be adjusted when playing more than 1 spot due to slower play. Specifically, on page 163 of "Blackjack Attack": "If the play-all shoe player always payed two spots, the raw SCORE would be improved by a factor of 1.46. We have to deflate this due to slower play. From Wong's data, the number of rounds falls to 83.5% (from 91 rounds per hour down to 76, using 4/6 game as an example)."

Some followup questions:

Assume the AP is playing alone at the table.

1) How should the raw SCORE be adjusted for slower play for 3 spots, 4 spots, and n spots?

2) Where does Wong's data source come from and how is it derived?

3) What are the expected raw SCORE improvements for 3 spots, 4 spots, and n spots?

SCORE is per 100 Rounds. 100 Rounds is 100 Rounds. SCORE goes up by 1.46 because when you're betting optimally you're betting 1.46 more money per round so your EV is 1.46x higher. (Most people bet 1.5x to simplify calculations). e.g., Two hands of $73 has the same risk as One Hand of $100. But you've got $146 on the table.

1) I understand how the raw SCORE will improve by 1.46 playing 2 spots, but also the SCORE must be adjusted down 16.5% for slower play. How did Wong derive the 83.5% number?

2) What are the expected raw SCORE improvements for 3 spots, 4 spots, and n spots? And what are the corresponding slower play SCORE adjustments for 3 spots, 4 spots, and n spots?

No it must NOT. SCORE is always based on per 100 Rounds. Speed is irrelevant. You are likely somehow confusing SCORE with EV. SCORE as a comparative device was developed well after Wong wrote his books, I don't even think DI was around as a tool for comparing games when any of Wong's books were written (excepting his Dice and Sportsbetting books).

If there are differences in the SCORE due to playing multiple spots (or playing with other players) it has more to do with card eating issues and the changes in hand frequencies at each True Count rather than speed which is already accounted for because of the standardized definition of SCORE.
