I can get over 300 (without any friends helping).
As a a tip i would say that you should try to be as calm as possible and focus your eyes on the second screen. It doesnt matter where you focus your eyes, you will still see all screens, but since there are so little space between the arrows you have to focus a little extra on that.
Move around with WASD all the time. If there aren't any boxes, just move around in cirkles or something.
If things are getting out of control, the first thing you need to do is to ignore WASD for a couple of seconds untill you have sort things out. If things realy are getting out of control you can also ignore the fourth screen and hope that you dont have to change anything there.
