How does the % in ranked work?

Dumb question. Do i want my % to go up (40 up to 45) or down (40 to 35)? I know in G4 you wanted it to go up, to 100%. I have had my % move both ways after a win or a loss. It does not make sense.

You want it to go down. The % tells you where you stand against other people in your rank. If it’s 35% that means you’re the in the top 35% of your rank
