Without seeing the actual code for how it works, you’re making an educated guess. You may be 100% sure, but I don’t think you’re right. There are also other possible scenarios: you can increase your buildr score by 2 even if you don’t get anything in the forum at all. You can increase it by 1 if you get nothing in the forum. This can happen regardless of whether your dead entries got any upvotes. In my experience, it depends on your ratio of upvotes to downvotes or just a simple calculation of final positive score minus the negatives. I would bet that an average score is calculated each week and that your score increase depends on how far away from the mean you are (modified by whether you get anything into the forum).
