You CAN save time in a speedrun by being able to clip through the very first Fredbear sprite in the beginning before the glitch. How you do this is the same way you would clip through Fredbear the second time in Choppy's Woods, but right before you would collide with Fredbear, immediately click "Bytes" and "Done" as fast as possible while holding the "S" key and the "A" key to be going down and left. If you are running the game at 60+ FPS and not lagging, you should be able to clip right through the Fredbear and continue along your run. Remember though that this does not work for Clock Ending speedruns.
