Well, it really comes down to how confident you feel about the first clue. Some folks really like to optimize the amount of points they're getting and what their average is...so if they really don't know it and guess wrong then the max they can get that day is 3 points. Versus a 4 which could help their overall average. If you're only looking at it from the perspective of a streak and guessing something, then it really doesn't make a difference.
