My best answers percentage has been only 2% for 4 years. Why? Even when i get favorite answers ranked?

Orthodoxy is the only true faith. Rapture = heresy; Fireball (aka Shadowfire aka Corvus Blackthorne aka Nightwulf aka Reynaldo Weeks) should be beheaded for spreading this heresy on Yahoo Answers (deceiving Christians into false hope). Dreams/thoughts are from 1)angels who always do good; 2)demons who never do good; or 3)you making shyt up in your head while you sleep trying to solve your problems; or from 4) your gov't using this supertechnology. Usually, dreams/thoughts are from demons. So, that explains a lot of people being in the wrong all the time. Rapture thing is from demons but you can't rule out the gov't using some super technology like Project Blue Beam to kind of introduce people to the evil flying antichrist who will ride on a donkey into the Third Temple. So, churches who closed for COVID (or had COVID measures like dipping spoon into some liquid like alcohol) are no longer Christ's but now are working for Satan promoting the new COVID religion. Last Patriarch is Patriarch Irenaios 1st. He blessed Catacomb movement. For liturgy what you need is antiminis (towel with remains of saints sewn into it); wax candles; one cup/one spoon; non-Kosher non-yeast non-barcoded non-qrcoded wine/bread. Kosher = sprinkled with blood. Yeast is grown on pig bacteria. QRcode = barcode = mark of the beast. Roman Catholics tried one cup and one spoon and got sick with Bubonic plague (no laughing matter). You must hide (within a small group of 10-15 people according to saints Gabriel Urgebadze and Seraphim of Sarov) in order to escape the unforgivable mark of the beast. No documents once you hid because documents are from Satan; burn all the documents that you can find. No electronics once you hid because antichrist's minions will track you using electronics that you got. Even old broken unplugged 1970 TV set will show the antichrist using Tesla's ether. In case you're in 'Murica and want to hide, then consider inland Alaska. Arctic Circle = Security Circle for WW3. If you manage to escape the unforgivable mark of the beast, then your direct ancestors will go to heaven (according to saint Vyacheslav Krasheninnikov). Thanks for reading this spiel. Forgive me.

Access to your profile would help. Here is an example. If you have posted 1000 answers, 2% means you got 20 BAs. If you answer 15 more and get BAs for all 15, the percentage will change to 3%. That is the barrier. Do the math:

% = 100 X #BAs / Total # of Answwers

they havent changed any of that lately

The "rank" doesn't matter.  That percentage is based on the number of questions you have answered compared to the number of those questions that get picked to be "best answer".  

If you answer 100 questions and 2 are picked for "best answer" - then your "best answer" percent is 2%.  

If you have answered 1000 questions and 20 have been picked as "best answer" - then your percent is still just 2%.

If you are trying to increase your percent, then answer only questions that you think you honestly do have a good answer for.  Stick to topics you know.  Avoid giving generic answers just to get points.  Also try to avoid answering questions that are obviously "troll" questions.  These trolls are usually using multiple accounts and will end up giving away "best" answer to one of their own troll accounts.  

If I had to guess, you spend time just giving short answers to lots of questions instead of giving thoughtful answers to just a few questions.  Of course, since you posted as anonymous, I can't see your history to see if my guess is accurate.

I used to have very high numbers.

Fact is, the more questions you answer...the percentages will go down even if you receive 10 points every time.

It's a numbers game.
