I know I can go here to see my rank in a particular tag. But is there a way to see at what percent I am in?
The following SEDE query gives you that result:
; with tagleague as ( -- build score and count per user select p.owneruserid , sum(score) as score , count(*) as posts , rank() over(order by sum(score) desc) as tagrank from posts p inner join posttags pt on pt.postid = coalesce(p.parentid, p.id) -- questions have tags inner join tags t on t.id = pt.tagid where t.tagname = ##tagname:string?java## and p.owneruserid is not null and posttypeid in (1,2) -- Q/A group by owneruserid ) select owneruserid as [User Link] , ( cast(tagrank as decimal) / (select count(*) from tagleague) * 100 ) as perc , (select count(*) from tagleague) as total , tagrank from tagleague where owneruserid = ##userid:int?1475228##
When run today your percentage is:
Keep in mind that SEDE is only updated weekly, in the weekend.
