Every pro's CT position, where he goes first on T, his role and his opening duels, on every map, measured from tournament demos.
CS2 demos store, for every player and every moment, the in-game area he is in (the callouts you see on the radar). CT position is the area he holds between 15 and 30 seconds of each CT round. "Goes first on T" is his area in the first 18 seconds. The confidence tag shows how many rounds a number is built on.
