I'm concerned that the rating metric is wrong in penta when reviewers leave one of the three categories in a "don't know" state. for example, if i say "+" for all three categories (relevance, actuality, acceptance), the score will be 50. (50 + 50 + 50)/3 if i say "+" for relevance and acceptance, but "0", the score shows 37. This seems slightly wrong -- i'd have expected 33. but meh, not a very big deal. A bigger deal is if i say "+" for relevance and acceptance, but leave actuality as unspecified (because i don't know anything about the presenter), the score also drops to 37. I'd have expected it to stay at 50: (50 + 50)/2 In particular, i'm proposing that unspecified axes should be removed from both the numerator and the denominator, rather than just being treated as a 0 in the numerator. Any thoughts on this? Am i misunderstanding something? --dkg
