I've been browsing the unanswered questions, partly because Area 15 says:
71% answered: Needs Work – 90% answered is a healthy beta, 80% answered needs some work.
However I've found some "unanswered" questions really were answered, for example:
Crash when using std::queue. That had a perfectly good answer by Edgar Bonet, however he did it as a comment, not an answer so it didn't count.
What could cause interrupts from MCP23017 suddenly stop working? - the OP worked out the problem and acknowledged that in a comment, however the question went "unanswered".
Attiny85 programmer with Arduino error Yikes! Invalid device signature - again, answered in the question comments, and acknowledged as such by the OP.
After putting Arduino Uno into DFU mode, it is no longer recognised by PC - the OP is asked for clarification but doesn't respond so the question lapses.
It seems to me unfair that these questions go into the "29% unanswered" bundle when they really were answered, or the OP simply lost interest (probably got it answered somewhere else).
Does this seem right? Is there a way of fixing up these statistics in some way?
