When you reply to someone (I usually do something like, "Thanks,") on a question you've asked, it counts that comment as an answer to go towards your Best Answer Percentage. I don't think this is fair because: 1.) There is no way you can select your answer as a Best Answer (I would never do this, though), and 2.) It goes towards your Best Answer Percentage. In addition to routinely submitting to instructables, I also try to improve my stats (total views, comments, subscribers, ect.). So, my Best Answer Percentage (in addition to many other's %, I assume) has gone down because our answers on our own questions count towards the Best Answer Percentage. Instructables staff, if you could change this, I would be very appreciative. Thanks!
