You are correct, it doesn't have any material impact on profitability.

The issue OP is describing, however, is a real difference in the software/methods be taught by BJ Apprenticeship and it definitely is confusing once you realize it exists. It is frustrating when you are trying to learn and one training tool says 'do X' while another says 'do Y'.

And I have myself setup CV blackjack where flooring vs. truncating is indeed relevant, because you don't get what you would expect.
