Finally started playing at speed 11! What speed do you guys play at?

When I started the game, I was playing at 6.5 speed, then I gradually went faster and faster and today, I've finally set my speed at 11 after almost 5 months of playing. I'm curious at what speed the average player here plays at, and whether or not I should aim to increase my note speed even more

And no, it's not a factorial! I see you math nerds coming at me, I'm not playing at an incomprehensibly high speed!!
