I also have a similar program in my statistical significance tools, that is fast and accurate. Also note that Steve's program has a little bug. Results are off by one unit. For instance, for your screen shot, 13-5 gives a confidence of 96.8%, but 12-5 gives 95.2%. So only 12 wins are required to ensure 95% confidence with 5 losses. Rémi
