https://saliu.com/skip-strategy.html
“The skip is simply the number of drawings between two hits of a particular lottery number (digit). The skip is calculated here as number of drawings back. If, for example, a lotto number hit in the very last drawing and previously in drawing #3, then the skip is equal to 2: 3 - 1 = 2. We can say that the lotto number hit last time 2 draws back. You can also think the skip as the gap between two hits, or as hit-and-miss count.”
