I'd like to know why I keep getting best answer and never ask a question, but my % goes down from 14 to 13 ?

The best answer % is the number of best answers divided by the total answers given times 100 so your % will go up & down with the number of answers given.

It's simple math. Your best answer percentage includes the questions that are unresolved, where the asker has not chosen a "best answer" or where it's in voting.

Look at it this way: you have answered 4 questions and won "best answer" on 1. You have a 25% "best answer" rate. Then you go and answer 6 more questions. Now you have a 10% "best answer" rate even though nobody's won "best answer" on the 9 questions you answered that are still pending (the 3 from before and the 6 you just answered). Your % dropped but it's only because you answered more questions.

Make sense?

your % of best answers is based on the ratio of best answers to total answers - doesn't have anything to do with asking questions

The yet unresolved questions count against your percentage.

it is bassed on your answers once you ahve many answers it will stablize more mine doesnt move to much anymore in fact it hasnt changed in about a month or so
