My 2nd top play of that session. I didn't really consider this to be completely out of the blue, as I had done a playthrough with 4-100's a month or so back, and minutes before this I had set an S-rank 3-100 as a proof of possibility to Manish and Emine.
I did have some issues with speed control, but obviously it wasn't so serious that I couldn't overcome them. Remembering to play the bursts/streams on the beat helps a lot in that regard.

Osu! also has different rankings you can shoot for, with SS being the best (Hit every note and have 100% accuracy).
