- * fail?
- * 2. How much will give a reasonable chance of qualifying, given the expected performance
- * of all the others?
- * 3. How much will be enough to secure qualification, no matter what?
- *
- * Given perfect guessing, #2 would be "how much is needed to qualify"; however, it is
- * completely impossible to give an exact value for that, and we're not into the guessing
- * games. :-) #1 is often so low it's completely unrealistic (ie. far enough from #2 that
- * it's not interesting), but #3, the most conservative estimate, is often a good measure.
- * #3 is "how much is needed to _secure_ qualification", and that is usually what we
- * print out when it's possible.
- *
- * However, in a few situations, #1 and #3 will be the exact same value, from which it
- * follows (from the squeeze law, or just common sense :-) ) that #2 will be the same
- * value as #1 and #3. (This usually happens near or at the end of a group.) In that
- * case, we know the value we seek (ie. "how much is needed to qualify"), so we drop
- * the word "secure" and just print it as-is.
- *
- * To find #1 and #3, we sort and pick out the values we need to beat in the best and
- * the worst case.
