BA% =

number of BAs / total number of answers X 100

When you answer without getting BAs, the % can go down. To increase it, you must get a higher % on new answers compared to your current level.

For example, if your current % is 15%, you need to get 20-25% on new answers to really change it. It is much easier for it to go down, than to go up.

It's the percentage of how many of their answers are Best Answers.

It's the % of questions you get best answers on from the amount of questions you have totally answered.
