All of the odds threshold calculated here seems to correspond to the "confidence level" nicely (at least pretty close most of the time), meaning that:


 * For Very Easy, the winning rate is 95%, and therefore 95% of the time the level can be completed in one attempt. For 98%, it can be completed in two attempts.
 * For Easy, the winning rate is 80%, and therefore 95% of the time the level can be completed in two attempts. For 98%, it can be completed in three attempts.
 * For Somewhat Easy, the winning rate is 60%, and therefore 95% of the time the level can be completed in four attempts. For 98%, it can be completed in five attempts (qualifying "one set of lives").
 * For Medium, the winning rate is 40%, and therefore 95% of the time the level can be completed in six attempts. For 98%, it can be completed in eight attempts (The page lists 10 due to rounding).
 * For Somewhat Hard, the winning rate is 25%, and therefore 95% of the time the level can be competed in eleven attempts. For 98%, it can be completed in fourteen attempts (The page lists 15 due to rounding).
 * For Hard, the winning rate is 15%, and therefore 95% of the time the level can be completed in nineteen attempts. For 98%, it can be completed in twenty-five attempts.
 * For Very Hard, the winning rate is 10%, and therefore 95% of the time the level can be completed in twenty-nine attempts. For 98%, it can be completed in thirty-eight attempts. (Saying this one might take 40 attempts might seem more suitable unless the chance is 8%, in which case it would take 36-47 attempts.)
 * For Insanely Hard, the winning rate is 3%, and therefore 95% of the time the level can be completed in eighty-nine attempts. For 98%, it can be completed in 119 attempts. (If the rate is lower like 2%, it would be 149-193)
 * For Nearly Impossible, if it might take 1000 attempts, then the winning rate might be 0.4%, in which 95% of the time guarantee the level can be completed in 748 attempts, while 98% of the time guarantee it takes 977 attempts.
