To find your DNF Ratio, visit your "My Geocaching" log page and click on the "Didn't Find It" and "Found It" links to get your total number of logs for each. (The number will be near the top of the page and will say "x Results") Now divide your total number of Found-It logs by your total number of DNF logs to get your DNF Ratio.
For example, we have 60 DNFs logs and 369 Found-It logs. So:
369 / 60 = 6.15
That means we average a DNF about every 6 finds. Pretty sad, isn't it? This came to my attention last weekend, when we had a record SIX DNF logs in one day.
What's your DNF ratio?
