What is the OSR?

[Julio88]

The overall system rating (OSR) in blackjack is a measure of the effectiveness of a card counting strategy .The OSR is calculated as the ratio of the expected win rate with a particular betting strategy to the expected win rate with a flat bet of the same size. In other words, the OSR compares the performance of the card counting strategy to a basic betting strategy of always betting the same amount. A higher OSR indicates that the counting strategy is more effective, while a lower OSR indicates that it is less effective.
The OSR can be used as a performance metric when comparing different card counting systems. For example, a system with a higher OSR may be considered more effective and therefore more desirable for use in real-world playing situations.

Exactly! The OSR is an important metric that players can use to compare the effectiveness of different card-counting systems. It helps them determine which system offers the highest expected win rate and therefore the most potential profit over time. However, it's important to note that the OSR is just one factor to consider when selecting a card-counting system. Other factors such as ease of use, accuracy, and camouflage ability also play a role in determining which system is the best fit for each individual player.
