I registered just so I could post to this crazy discussion.
First, the OP seems to be arguing semantics on the word "chance". Coincidentally, a company by the name of Kabaam also uses the word "chance" with equal misrepresentation in their mobile game "Hobbit KOM". They advertise paid items as "a 100% chance to win X Y and Z items". What they mean is that they "guarantee you a chance to win something" not "they guarantee you win X Y and Z".
Here what the OP seems to be saying is that the word "Chance" implies a "chance at a probability" rather than the probability itself. In that he is completely incorrect. Chance and probability associated with a number are synonyms. From the Miriam Webster dictionary:
Probability =- the chance that something will happen
Chance - the possibility that something will happen
If you put $1 in 4 pockets, people will have a 25% chance, or a 25% probability, or a 25% possibility to identify the correct pocket. The use of Probability or Chance (or possibility) is interchangeable.
You could also incorrectly state that they will have a 100% chance to guess which pocket the dollar is in. The incorrect logical jump with that statement is that there is a 100% chance at a 25% probability. The first use of 100% in this sentence is redundant. There is no need to state that, since the key to the probability math is the 25%.
With regard to the OP and archery specifically, a 100% chance to hit is not implying that you have a 100% chance at a xx% probability. It is stating the probability/chance/possibility. The argument is specifically about the semantics of the word 田hance and the use in a sentence.
Also, by the rude nature of his response to patient members of the community, he is either a troll himself someone that really needs to have a cup of herbal tea and relax a little
