Remarks

The confidence threshold is the amount that the score of the highest-scoring in the current key set must be above the highest-scoring character that has a non-zero confusion score with any character in the keyset.

If a potentially confusing character has a high score than the highest-scoring key set member, the status of the result is always Confused, but the returned key will still be the one from the key set not from the confusing key.

Only keys that pass the confusion threshold test are considered for this scoring or verification step.
