One recent revelation was a surprise

I have been working on programs to play lotteries since last July, when I started prototyping. In the last day, I have been testing performance with a range of numbers for playing Cash Five (Texas). I had always assumed that generating combinations from a greater number of numbers was superior to a smaller number. I proved to  myself today that is incorrect. Playing as few as 11 hot numbers was better than playing 33 hot numbers. This is using a "full wheel" with random selection of combinations to play. One of my tweaks was to randomly select small blocks of combinations, and that often is better than a file of single random selections.
