  1. This is a great resource for getting a confidence interval out of a small sample of events! If I got 3 hits for 1 day (95% Confidence Interval = [0.61867, 8.76727]), I can expect 18.5 to 263 hits per month. If I got 30 hits today, I can expect 607 to 1284 hits per month. Is my interpretation correct?
