Somewhere inbetween? You want to go fast but not so fast that you miss every shot. I sit between 90-95% on most my static runs, and as you get used to a certain speed, i.e. getting to 97+% you should speed up more.

Definitely fast. Try to focus on having a clean and controlled landing. What frosty said about acc percentage is good advice too
