Chebayev took the standard normal disribution as a model of random noise distributed over a mean. He proved that limits on the range or type of distributionn would result in a Fournier type series of sinusoidal outcome paths. That was used by economist Kondratiev, for his work, who modeled social and economic stress tolerance in an economy causing macro-economic wave patterns. Kondratiev was killed by Stalin in 1931 who alleged that such trivialized the Bolshevic revolution as just a bad capitalist downturn and not the start of a new socialist society.
Chebayev is most known however for showing how distributionn limits are models of resistance, capacitance and inductance, in electrical networks. Anyone who has been involved in filter design in Ham Radio or EE classwork has used these same equations.
Ruin equations also follow this same interchangeability. It is no more correct to say a properly derived ruin equation is better or worse than any other than it is to decide that nothing smaller than a 3 pole Chebayev filter should ever be used. Same math! In fact band pass rejection follows the same math exactly!
Lately ML and Cyrus have posted below using past ruin equation disputes between myself and DS as a card to play against any discent with their views. They promote an agenda of claiming: to disagree is wrong.
I appeal to past fellow ee majors and Hams who count and understand blackjack (sorry Frank, no!) for their comments which I am sure will excede mine, and my examples and explanations here. Alternatives abound and "one true path" is typically wrong for all. That is why I use the term: clones. Clones all have the same vulnerabilities for fluctuations, conditon changes and detection by the other side.
Stanford Wong has revised the posting standards to prevent actually posting such information, but it should be noted that you can take any book, such as BJA or BJA II, and from the advice sugested, come up with exactly the game rules, shoe size and shuffle point that will finger anyone using such in a very short time.
The fact is that as conditions tighten, the clones draw heat away from the mix of tactics that I use. But it would get very boring not having anyone to compare notes with, online or face to face.
