The Van Keelen Test

The Van Keelen Test

Every serious system player is interested in an objective method, giving him information whether his system has a certain value and is going to produce a net profit in the long run.

Beside the "Statistical Ecart" and other test options, with which we will deal in one of the next issues of Basics, "the Van Keelen Test" is a simple measuring procedure, with which the player can determine the chances of success or failure of his system.

The Van Keelen Test, which was developed decades ago, will give the player information about the value of a system, and requires the player to check his system over a certain number of placed bets before he begins the practical play.
This again has the advantage that possible losses only develop on paper and not in reality at the table!

The Van Keelen Test sets into relationship the net gain of a system to the number of placed bets, whereby the minimum number of the placed bets checked for all chances must amount to at least 1000.

The units wagered must be of equal value; no progression is to be used! It is very important to point out that we speak here of placed bets, not spins!
To check a system over 1000 spins, has no meaning!

This testing method has the inestimable advantage that a system must be checked at least over 1000 placed bets, and on this basis a prediction about the value of the checked system is possible.

With 100000 *checked bets, even a negative result can be still another feature of a good system. Because if a system indicates a real superiority over ZERO, the possibility exists, that with an adapted progression continuous gains can be obtained.

1. if after 1000 placed bets a gain of more than 100 units was obtained!

3. if after 100000 placed bets a result better than - 1000 was obtained*

Twelve-Number-Bets (Dozens/Collumns):
A system indicates a genuine superiority:
1. if after 1000 placed bets a gain of more than 50 units was obtained!
2. if after 8000 placed bets a gain of more than 50 units was obtained!
3. if after 100000 placed bets a result better than - 2000 was obtained*

Six-Number Bets (Lines):

1. if after 1000 placed bets a gain of more than 100 units was obtained!
2. if after 8000 placed bets a gain of more than 200 units was obtained!
3. if after 100000 placed bets a result better than - 600 was obtained*
