Don Schlesinger confirms low Risk of Ruin for short stack

On page 160 of the classic "Blackjack Attack" table 9.4 offers the following:
Playing Hours: 1
TRIP BANKROLL REQUIREMENTS: 21 (units)
Expectation in units won:2.5
Risk of Ruin: 40%
[2-deck, favorable rules, 6 to 1 spread, 75% dealt]

40% Risk of Ruin is a far cry from the 90-100% figure given by several on this topic in several threads below. (albiet for single deck action)
I estimated 15% risk of ruin for just 3 rounds dealt, single deck.
Given Schlesinger's figures, that sounds about right.
This should settle this ridiculous argument.

40% is your risk of ruin for 1 HOUR. You would likely face a similar chance of busting out each and EVERY hour. How many hours in a row do you expect to survive when you have a significant chance of busting out each hour?

And if you think 40% is a "low risk of ruin," put down the crack pipe.

The only thing ridiculous is your arrogance and inability to absorb knowledge on this topic. You will learn the correct answers at the tables (at a huge cost) since you refuse to learn them here.

. . . which was that he wanted to play for a short period with his hundred bucks, not an indefinite one! He wanted a taste/sample of the AP experience, not to sit for long hours.

1 hour session=about 40% chance of ruin. (I understood this point when I rec. busting out or doubling the stake or leaving after 1 hour with a few extra chips in his pocket.) Please review the thread.

Please try and cool your temper and insults! And I don't do crack.

As for my knowledge and experience of the game I am averaging 10 units win per hour at green level for this year.

Yeah, sounds like a pretty hot tip for Van Gogh. Good work.
