Can go fast... just control the distance from the urinal. as the
pressure gets lower, you go nearer and nearer, than until finally
you shake it and zip up.
You should can start once you enter the room, and shoot at an
available urinal immediately. remember that aiming 45 degrees up
give you max distance.
than you will need to control your stream and move towards the
urinal at the same time. try to keep the pressure up, so you won't
need to move too fast. remember, moving too fast affects your
aim.
some advice: never shoot over another person.That is just not
very nice.
