I imagine it was a percent measured against successful responses. The exceptions now far exceed those successful responses. You are correct in saying it should

  If this is in fact how they're measuring...I was going to make this post a long rant about how ridiculous it is to measure it in that way, but then I realized that people do sometimes measure probabilities by quoting the win-to-loss or loss-to-win ratio. This is called "odds" and frequently used in gambling. Usually, though, someone says "4.7 to 1" or "47 to 10" (abbreviated 4.7:1 or 47:10) instead of 470%. Usually the larger number is stated first, and the direction is usually indicated by a word like "favorite" or "longshot." So one would say "Errors seem to be a 4.7:1 favorite today." It's slightly complicated by the fact that odds can measure one of several things: A. A probability ratio ("Red" is a slight underdog in the game of roulette [1]; the odds against hitting it are 20:18 since there are 20 non-red spaces and 18 red spaces) B. A payout ratio ("Red" pays 1:1, meaning the prize if you win this bet is equal to the amount of the bet) C. The current payout of a paramutuel pool [2] Odds are seldom used outside of a gambling context.
