Keep in mind 10 character spaces should be represented by the selection pool size (A-Z = 26, a-z = 26, 0-9 = 10, so 26+26+10=62). You now can say 62^10 = total

Keep in mind 10 character spaces should be represented by the selection pool size (A-Z = 26, a-z = 26, 0-9 = 10, so 26+26+10=62). You now can say 62^10 = total possible guesses available. Certainly you can start to make intelligent decisions on guessing properties and priorities to reduce your time. Also I didn't discuss entropy here in order to represent it more basically for the parent comment.
