Hello psykomo. There are various ways the numbers can be broken down. For example, you can break the numbers down according to sums, root sums, e.t.c. With this, I decide on one of these ways to get my numbers. But, a breakdown that gives me more numbers ,to play, and not less. You need more numbers to increase your chances of winning.
Secondly, there's the calculated play. When playing more numbers, you have to control your losses. You can't just play a lot of numbers on every draw. You'll run into bad losing streaks. An example of calculated play is with EHR(i.e. Expected-Hit Rates). This has to do with how often different types of numbers are expected ,on average, to hit. For example, the EHR for Consecutive-Digit Numbers(e.g. 012,123,234, and so on) is 1 in each 16 drawings. Another example is seen with doubles. In this case, The EHR is 3 doubles in each 10 drawings. The EHR can help you with knowing when to start playing. Hope this helps.
