Have tested "Mikes Ladder" well over 100,000 rolls. Very successful. Just have not had time to write software to test millions of rolls. Like I said. Bought WinCraps have no idea how to program it. My latest thoughts are: Find a way to collect a list of people who want to buy "Mikes Ladder" outright. At the same time collect a list of people who would receive "Mikes Ladder"about a moth after I release it to the people who buy it outright. I am working on a website.
