Ok, let's see...
About 2): As I stated in the first post of the relevant discussion thread, the users do suggestions, but the selection committee reserves the right to reformulate them or give them another interpretation. Regardless of that, what you're saying in this case is not true. Here is the post where you made suggestions and you wrote "individual medals":
About 3): Why does that matter? the predictions (and subsequently, the results) are set in stone since the deadline of February 9th, it's not like any participant can go now and edit their predictions according to what you say here. In fact, anyone that does that would be DSQ. This is a "one phase" contest.
About 1): We are not perfect, far from it, and that's why we make mistakes. Sometimes some ambiguities or lack of clarity in the bets flies under my radar. In this case, somehow, we made a mistake and deleted the word "individual" from your original suggestion. I don't know how that happened and I apologize deeply for that.
Since the last contest I established a policy that in the case any user presents to me a problem with the meaning of a particular bet in the discussion thread AFTER the contest has already opened and AFTER several users have already posted predictions, I would then clarify the meaning of that bet in the discussion thread. No one objected to this policy neither 2 years ago nor now, therefore, I understood that the participants gave tacit agreement to it. I'm just asking users to read the specific discussion thread created for this contest (that is apart from the regular prediction discussion thread), I don't think that's asking too much honestly.
In the case of this particular bet, one user asked about the relays' problem (this was BEFORE the deadline) and I answered that according to our interpretation it doesn't take into account relays. The reason: we simply thought including the relays made the bet easier than what we wanted it to be.
Later (AFTER the deadline), another user warned me of some ambiguity problems with bet number 58 and since it was after the deadline (so, users couldn't edit their posts anymore, unlike with bet 60) I decided to award the invested points for both YES and NO.
