Yep they dont add to 100%.

Because it's a multiple choice poll, not a single choice one.

The middle option only adds up to 100% the other 2 adds up to 60%.

Oh, I see. Well, people didn't understand how to fill in the poll. (The poll itself cannot check anything, the "multiple choice" mode gives multiple possible answers to a single question. There's no mode that would allow answers for multiple questions.) Gotta do something about it. [...] Hopefully fixing the title will take care of it.

As only 6 forum members have voted for this poll, the results can hardly be called representative for the whole forum so the rules won't change. The poll may be reopened empty within some months or something; better luck next time.
